computer vision research topics 2019

The paper was presented orally at ICML 2019, the leading conference in machine learning. Please note that I picked select papers that appealed the most to me. For example, many methods in computer vision are based on statistics, optimization or geometry. Currently, depth reconstruction relies on having a still subject with a camera that moves around it or a multi-camera array to capture moving subjects. Image detection algorithms struggle with large-scale detection across complex scenes because of the high number of object categories within an image, heavy occlusions, ambiguities between object classes, and small-scale objects within the image. This object-recognition dataset stumped the world’s best computer vision models . This field is a combination of computer science, biology, statistics, and mathematics. an object has moved). Exploring the links between the geometric approach described here and newly introduced backprojection approaches for profiling hidden objects. Suggesting a model that is able to recreate depth maps of moving scenes with significantly greater accuracy for both humans and their surroundings compared to existing methods. The resulting method can reconstruct the surface of hidden objects that are around a corner or behind a diffuser without depending on the reflectivity of the object. Introducing a new CLEVR-Change benchmark that can assist the research community in training new models for: localizing scene changes when the viewpoint shifts; correctly referring to objects in complex scenes; defining the correspondence between objects when the viewpoint shifts. Make learning your daily ritual. One interesting learning for me was the architecture of the Graph CNN used for mesh generation. The figure below shows BubbleNets architecture and process for bubble sort. Object Detection 4. Technically, computer vision encompasses the fields of image/video processing, pattern recognition, biological vision, artificial intelligence, augmented reality, mathematical modeling, statistics, probability, optimization, 2D sensors, and photography. They introduce a gold standard human benchmark, Human eYe Perceptual Evaluation (HYPE), to evaluate the realism of machine-generated images. Then, the model identifies close neighbors, whose embeddings are similar, and background neighbors, which are used to set the distance scale for judging closeness. 3. Research Interests : I have been fascinated by many topics in computer vision and machine learning. We then derive a novel constraint that relates the spatial derivatives of the path lengths at these discontinuities to the surface normal. Computer vision is the science and technology of teaching a computer to interpret images and video as well as a typical human. EfficientNet: Rethinking Model Scaling for Convolutional Neural Networks, by Mingxing Tan and Quoc V. Le.

Includes Computer Vision, Image Processing, Iamge Analysis, Pattern Recognition, Document Analysis, Character Recognition. These differences result in a significant discrepancy between the size of objects at training and at test time. Keywords: Computer Vision, Pattern Recognition, Artificial Intelligence . Existing methods for profiling hidden objects depend on measuring the intensities of reflected photons, which requires assuming Lambertian reflection and infallible photodetectors. However there is also continuous risk of face detection being spoofed to gain illegal access. In this post, we will look at the following computer vision problems where deep learning has been used: 1. The basic architecture of CNNs (or ConvNets) was developed in the 1980s. By reading this list many ideas can be gathered by the graduates for their research paper topic in cybersecurity. The representation resulting from the introduced procedure supports downstream computer vision tasks. Computer vision is an inter-disciplinary topic crossing boundaries between computer science, statistics, mathematics, engineering and cognitive science. The RCM framework outperforms the previous state-of-the-art vision-language navigation methods on the R2R dataset by: Moreover, using SIL to imitate the RCM agent’s previous best experiences on the training set results in an average path length drop from 15.22m to 11.97m and an even better result on the SPL metric (38%). CiteScore: 8.7 ℹ CiteScore: 2019: 8.7 CiteScore measures the average citations received per peer-reviewed document published in this title. I am extremely passionate about computer vision and deep learning in general. I created my own YouTube algorithm (to stop me wasting time). In 2019, we saw lots of novel architectures and approaches that further improved the perceptive and generative capacities of visual systems. The introduced deep neural network is trained on a novel database of YouTube videos in which people imitate still mannequins, which allow for traditional stereo mapping of natural human poses. Face anti-spoofing is designed to prevent face recognition systems from recognizing fake faces as the genuine users. In this work, we introduce a novel Reasoning-RCNN to endow any detection networks the capability of adaptive global reasoning over all object regions by exploiting diverse human commonsense knowledge. To help you navigate through the overwhelming number of great computer vision papers presented this year, we’ve curated and summarized the top 10 CV research papers of 2019 that will help you understand the latest trends in this research area. CVPR is one of the world’s top three academic conferences in the field of computer vision (along with ICCV and ECCV). A total of 1300 papers were accepted this year from a record-high 5165 submissions (25.2 percent acceptance rate). Creating such a data set would be a challenge. Research in computer vision involves the development and evaluation of computational methods for image analysis. Object Segmentation 5. In this paper, the researchers propose a new Reinforced Cross-Modal Matching (RCM) approach that enforces cross-modal grounding both locally and globally via Reinforcement Learning (RL). It is the current topic of research in computer science and is also a good topic of choice for the thesis. This finds applications in video understanding and has seen a lot of research in the last one year. Conversely, when training a ResNeXt-101 32×48d pre-trained in weakly-supervised fashion on 940 million public images at resolution 224×224 and further optimizing for test resolution 320×320, we obtain a test top-1 accuracy of 86.4% (top-5: 98.0%) (single-crop). A list of free research topics in networking is available to the college students below. We construct Human eYe Perceptual Evaluation (HYPE) a human benchmark that is (1) grounded in psychophysics research in perception, (2) reliable across different sets of randomly sampled outputs from a model, (3) able to produce separable model performances, and (4) efficient in cost and time. BubbleNets: Learning to Select the Guidance Frame in Video Object Segmentation by Deep Sorting Frames. Potential use for autonomous vehicles to “see” around corners. Learning the Depths of Moving People by Watching Frozen People, by Zhengqi Li, Tali Dekel, Forrester Cole, Richard... 3. We experimentally validate that, for a target test resolution, using a lower train resolution offers better classification at test time. In addition, the researchers introduce a Self-Supervised Imitation Learning (SIL) method for the exploration of previously unseen environments, where an agent learns to imitate its own good experiences. The navigator performs multiple roll-outs, and the good trajectories, as determined by the matching critic, are later used for the navigator to imitate. Epidemiology essay topics Patriotism beyond politics and religion essay pdf papers research 2019 vision Computer essay on national flag of india for class 1. This paper solves this by building a deep learning model on a scene where both the camera and subject are freely moving. To address this problem, the researchers suggest. Large-scale object detection has a number of significant challenges including highly imbalanced object categories, heavy occlusions, class ambiguities, tiny-size objects, etc. We show the superiority of our DUDA model in terms of both change captioning and localization. The images generated by the introduced model semantically resemble the training image but include new object configurations and structures. The difference in image preprocessing procedures at training and at testing has a detrimental effect on the performance of the image classifier: This results in a significant discrepancy between the objects’ size as seen by the classifier at train and test time. In this paper, we systematically study model scaling and identify that carefully balancing network depth, width, and resolution can lead to better performance. The experiments demonstrate that the DUDA model outperforms the baselines on the CLEVR-Change dataset in terms of change captioning and localization. Image Super-Resolution 9. User studies confirm that the generated samples are commonly confused to be real images. Fermat paths correspond to discontinuities in the transient measurements. Essay about part time job, title for essay about inequality! For example, they demonstrate that using lower resolution crops at training than at test time improves the classifier performance and significantly decreases the processing time. BubbleNets iteratively compares and swaps adjacent video frames until the frame with the greatest predicted performance is ranked highest, at which point, it is selected for the user to annotate and use for video object segmentation. See blog here. Conventionally, CNNs are first developed and then later scaled up, in terms of depth, width, or the resolution of the input images, as more resources become available. Enhanced security from cameras or sensors that can “see” beyond their field of view. Convolutional Neural Networks (ConvNets) are commonly developed at a fixed resource budget, and then scaled up for better accuracy if more resources are available. Please read through it if this is an area that interests you. Check us out at — http://deeplearninganalytics.org/. BubbleNets model is used to predict relative performance difference between two frames. For instance, we obtain 77.1% top-1 accuracy on ImageNet with a ResNet-50 trained on 128×128 images, and 79.8% with one trained on 224×224 images. The second method, called , measures the rate at which humans confuse fake images with real images, given unlimited time. Meetings are listed by date with recent changes noted. Using multiple frames to expand the field of view while maintaining an accurate scene depth. While advanced face anti-spoofing methods are developed, new types of spoof attacks are also being created and becoming a threat to all existing systems. Follow her on Twitter at @thinkmariya to raise your AI IQ. Relative performance is measured by a combination of region similarity and contour accuracy. can generate images that depict new realistic structures and object configurations, while preserving the content of the training image; successfully preserves global image properties and fine details; can realistically synthesize reflections and shadows; generates samples that are hard to distinguish from the real ones. I have taken the accepted papers from CVPR and done analysis on them to understand the main areas of research and common keywords in Paper Titles. Because the scene is stationary and only the camera is moving, accurate depth maps can be built using triangulation techniques. Computer Vision is a very active research field with many interesting applications. If you like these research summaries, you might be also interested in the following articles: We’ll let you know when we release more summary articles like this one. Generative models often use human evaluations to measure the perceived quality of their outputs. Be the FIRST to understand and apply technical breakthroughs to your enterprise. Reasoning-RCNN: Unifying Adaptive Global Reasoning into Large-scale Object Detection. 5 Reasons You Don’t Need to Learn Machine Learning, 7 Things I Learned during My First Big Project as an ML Engineer, Images used in the blog are borrowed from the papers. We demonstrate the effectiveness of this method on scaling up MobileNets and ResNet. We introduce two variants: one that measures visual perception under adaptive time constraints to determine the threshold at which a model’s outputs appear real (e.g. CVPR is one of the world’s top three academic conferences in the field of computer vision (along with ICCV and ECCV). Reasoning-RCNN does this by constructing a knowledge graph that encodes common human sense knowledge. Their approach is based on the notion that the internal statistics of patches within a single image are usually sufficient for learning a powerful generative model. To learn more about depth images and estimating depth of a scene please check out this blog. The paper has rich details on data set, training process etc. It involves only a computationally cheap fine-tuning of the network at the test resolution. We evaluate our procedure on several large-scale visual recognition datasets, achieving state-of-the-art unsupervised transfer learning performance on object recognition in ImageNet, scene recognition in Places 205, and object detection in PASCAL VOC. Unsupervised approaches to learning in neural networks are of substantial interest for furthering artificial intelligence, both because they would enable the training of networks without the need for large numbers of expensive annotations, and because they would be better models of the kind of general-purpose learning deployed by humans. To address this problem, the researchers introduce a simple global reasoning framework, Reasoning-RCNN, which explicitly incorporates multiple kinds of commonsense knowledge and also propagates visual information globally from all the categories. To improve the generalizability of the learned policy, we further introduce a Self-Supervised Imitation Learning (SIL) method to explore unseen environments by imitating its own past, good decisions. I love to work on computer vision projects. Image Segmentation/Classification. See t-SNE plot below. Computer Vision by Richard Szeliski The papers that we selected cover optimization of convolutional networks, unsupervised learning in computer vision, image generation and evaluation of machine-generated images, visual-language navigation, captioning changes between two images with natural language, and more. Image Synthesis 10. To tackle this problem, they introduce the Local Aggregation (LA) procedure, which causes dissimilar inputs to move apart in the embedding space while allowing similar inputs to converge into clusters. Check out our premium research summaries that focus on cutting-edge AI & ML research in high-value business areas, such as conversational AI and marketing & advertising. The depth (number of layers), width and input resolution of a CNN should be scaled up at a specific ratio relative to each other, rather than arbitrarily. However object detection is most successful when number of detection classes is small — less than 100. The model is trained and evaluated on 3 main datasets — Visual Gnome (3000 categories), ADE (445 categories) and COCO (80 categories). The paper received three “Strong Accept” peer reviews and was accepted for oral presentation at СVPR 2019, the leading conference on computer vision and pattern recognition. degree in School of Information Science and Engineering from … Describing what has changed in a scene can be useful to a user, but only if generated text focuses on what is semantically relevant. The Facebook AI research team draws our attention to the fact that even though the best possible performance of convolutional neural networks is achieved when the training and testing data distributions match, the data preprocessing procedures are typically different for training and testing. The 2019 IEEE Conference on Computer Vision and Pattern Recognition (CVPR) was held this year from June 16- June 20. To address this issue, the authors propose a novel weakly supervised method by leveraging depth map as a weak supervision for 3D mesh generation, since depth map can be easily captured by an RGB-D camera when collecting real world training data. Other Problems Note, when it comes to the image classification (recognition) tasks, the naming convention fr… Thus, the Facebook AI team suggests keeping the same RoC sampling and only fine-tuning two layers of the network to compensate for the changes in the crop size. Proposing a change-captioning DUDA model that, when evaluated on the CLEVR-Change dataset, outperforms the baselines across all scene change types in terms of: overall sentence fluency and similarity to ground-truth (BLEU-4, METEOR, CIDEr, and SPICE metrics); change localization (Pointing Game evaluation). achieving around 16% improvement on VisualGenome, 37% on ADE in terms of mAP and 15% improvement on COCO. A video description of the model is shared on youtube and source code is open sourced on Github. Many of its recent successes are due to advances in Machine Learning research. CiteScore values are based on citation counts in a range of four years (e.g. Introducing the Mannequin Challenge Dataset, a set of 2,000 YouTube videos in which humans pose without moving while a camera circles around the scene. As such, we demonstrate mm-scale shape recovery from pico-second scale transients using a SPAD and ultrafast laser, as well as micron-scale reconstruction from femto-second scale transients using interferometry. Here is a good introduction to the topic of Graph CNNs. Check out our website here. Subscribe to our AI Research mailing list at the bottom of this article to be alerted when we release new summaries. However, up until now, direct human evaluation strategies have been ad-hoc, neither standardized nor validated. Feel free to contact through the website or email at info@deeplearninganalytics.org if you have an idea that we can collaborate on. To the best of our knowledge this is the highest ImageNet single-crop, top-1 and top-5 accuracy to date. 3D Computer Vision in Medical Environments in conjunction with CVPR 2019 June 16th, Sunday afternoon 01:30p - 6:00p Long Beach Convention Center, Hyatt Beacon A. Currently, it is possible to estimate the shape of hidden, non-line-of-sight (NLOS) objects by measuring the intensity of photons scattered from them. 4. In particular, our EfficientNet-B7 achieves state-of-the-art 84.4% top-1 / 97.1% top-5 accuracy on ImageNet, while being 8.4x smaller and 6.1x faster on inference than the best existing ConvNet. I hope you will use my Github to sort through the papers and select the ones that interest you. Survey articles offer critical reviews of the state of the art and/or tutorial presentations of pertinent topics. See gif below: To create such a model we need video sequences of natural scenes captured by moving camera along with accurate depth map for each image. Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses.Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. A particularly challenging case occurs when both the camera and the objects in the scene are freely moving. Engineers (and scientists, too), firmly believe there are more advantageous applications to be expected from the technology in the coming years. As Research Mode is now available since May 2018, we are starting to see several interesting demos and applications being developed for HoloLens. Currently I am a computer vision researcher at SenseTime.Our team is developing fundamental perception algorithms for autonomous driving system. The introduced framework can be leveraged in many real-world applications, including: in-home robots moving around a home or office following instructions; personal assistants accepting verbal instructions and navigating a complex environment to perform certain tasks. But when those same object detectors are turned loose in the real world, their performance noticeably drops, creating reliability concerns for self-driving cars and other safety-critical systems that use machine vision. Welcome to the complete calendar of Computer Image Analysis Meetings, Workshops, Conferences and Special Journal Issue Announcements. Through optimization, the current embedding vector is pushed closer to its close neighbors and further from its background neighbors. The image below shows different types of spoof attacks. Based on this theory, we present an algorithm, called Fermat Flow, to estimate the shape of the non-line-of-sight object. I give you only one idea but minutely detailed idea--- Project title: Computer Vision identification of diseased leaves The project is divided into following phases--- (1) Image capturing phase You should form two teams. Initial depth is estimated through motion parallax between two frames in a video, assuming humans are moving and the rest of the scene is stationary.
