In this talk I will show how complex video analysis can be performed by exploiting the internal redundancy inside a single video. Composing internal chunks of the visual datum allows to make sophisticated inferences about dynamic scenes and events we have never seen before, in a totally unsupervised way, with no prior examples or training data.
I will show the power of this approach through a variety of example problems (as time permits), including:
1. Segmentation of unconstrained videos and images.
2. Unsupervised discovery of new video categories.
3. Detection of complex objects and actions (with no prior examples or training).

The task of category independent foreground segmentation in images is challenging for a machine learning system, because it needs to learn the general concept of an object, even for object categories that it hasn’t seen during training. In the case of foreground segmentation in videos, the problem is compounded by the fact that the object as well as the background change appearance throughout the video. We propose a method for learning the general concept of object appearance in videos, based on deep neural networks. Apart from learning the object appearance for each frame, our system learns the temporal changes between frames in a video, which represent the object motion, and thus leverages the temporal information available in videos. By learning a category-independent object segmentation, we are able to perform unsupervised video object segmentation. In addition, in the case of semi-supervised video segmentation (where one frame from the video is annotated) we further train our system to recognize a specific object which appears in the video. In both scenarios, our system compares favorably against the state of the art.
Furthermore, we demonstrate a novel use case for video object segmentation, by implementing a mobile application where a user captures a video of an object, and our system is able to segment the object and display it in an AR setting.

Trax is built to revolutionize the retail industry using cutting edge computer vision techniques. Our challenges include fine-grained visual recognition of densely arranged items in store displays.
In this presentation, we will introduce a novel CNN architecture which learns both local visual features and neighboring class representations, and extends the softmax function to define a probabilistic graphical model.
In test time, the graph is extracted from a context-enhanced detector, which converges into the correct localizations by iterative reduction of the attention regions, and refinement of object-proposal granularity.
The detected items are then classified by the marginal distributions of the graph joint probability, integrating local and spatial features.
We will further demonstrate how the algorithms can be optimized by dynamic programming techniques and parallel pipeline design.

Rare diseases affect one in every ten people. Many of these diseases are characterized by observable traits of the affected individuals - a ‘phenotype’. In many cases, this phenotype is especially noticeable in the facial features of the patients, Down syndrome for example. But most such conditions have subtle facial patterns and are harder to diagnose. FDNA has developed a unique, Computer Vision based solution called ‘Face2Gene’ - an AI engine of suggested syndromes and genes based on facial images of the patient. FDNA will present its solution, challenges and research aspects of the phenotype analysis.

Correctly matching feature points in a pair of images is an important pre-processing step for many computer vision applications. In this talk we propose an efficient method for estimating the number of correct matches without explicitly computing them. In addition, our method estimates the region of overlap between the images. To this end, we propose to analyze the set of matches using the spatial order of the features, as projected to the x-axis of the image. The set of features in each image is thus represented by a sequence. This reduces the analysis of the matching problem to the analysis of the permutation between the sequences.
Using the Kendall distance metric between permutations and natural assumptions on the distribution of the correct and incorrect matches, we show how to estimate the above-mentioned values. We demonstrate the usefulness of our method in two applications: (i) a new halting condition for RANSAC based epipolar geometry estimation methods that considerably reduce the running time, and (ii) discarding spatially unrelated image pairs in the Structure-from-Motion pipeline.

While augmented reality (AR) has been steadily gaining popularity in recent years, the majority of AR solutions are either mixed reality (MR), where graphics are not attached to specific elements in the scene, or marker-based AR, where graphics are anchored to a planar object visible in the scene. These solutions are often suitable for limited scenarios, but typical use-cases in the industrial domain require precisely anchored, marker-free AR. Our work in the Cognitive Vision and Augmented Reality group at IBM Research in Haifa focuses on research in AR for technical training, field maintenance, IoT, and other use-cases. In this talk I will present the group's AR platform and review some of the real-world installations in the industrial domain.

Mammography breast cancer screening over the past three decades has doubled the rate of early breast cancer detection and is credited with decreasing the mortality from breast cancer. Expert screening with current computer-aided detection (CAD) tools has sensitivity estimated between 68%-87% and specificity of 75% 91%. We present a mammography detection algorithm based upon machine learning techniques utilizing both public and proprietary training datasets. We used a committee of diversely filtered shallow Theano-based convolutional neural networks, pre- trained on ImageNet data and fine tuned using False-Color Enhanced Contrast-Limited Adaptive Histogram Equalized mammographic images. Our results yield accuracy of over 98%.
VR headsets use lenses to expand their field of view and to enable the viewer’s eyes to focus on the screen. However, the lenses introduce distortion in the image. This requires the graphic engine to render an image that is distorted in the opposite way, over-shading the outskirts of the image, rendering and shading a lot of pixels that will not make it to the displayed image. This is a significant inefficiency.
This talk will present two techniques for overcoming this inefficiency: Multi-Resolution Shading and Lens Matched Shading. We will also talk about NVIDIA's VRWorks and how it helps AR/VR developers.

Reconstruction of a full dynamic scene using a monocular moving camera requires reconstruction of both static and dynamic objects. We present a generic approach for simultaneous estimation of shape, location and velocity for static and moving objects using graph optimization. The main challenge is the unknown scale of each moving object; this is handled with a good initial depth estimation. For validation we created a dynamic simulation of an urban environment. On this simulation our method yields 13% velocity error when the camera is mounted on a car, and 2.8% velocity error when it is mounted on a drone.

Breathing monitors have become the all-important cornerstone of a wide variety of commercial and personal safety applications, ranging from elderly care to baby monitoring. Many such monitors exist in the market, some, with vital signs monitoring capabilities, but none remote. We presents a simple, yet efficient, real time method of extracting the subject's breathing sinus rhythm. Points of interest are detected on the subject's body, and the corresponding optical flow is estimated and tracked using the well-known Lucas-Kanade algorithm on a frame by frame basis. A generalized likelihood ratio test is then utilized on each of the many interest points to detect which is moving in harmonic fashion. Finally, a spectral estimation algorithm based on Pisarenko harmonic decomposition tracks the harmonic frequency in real time, and a fusion maximum likelihood algorithm optimally estimates the breathing rate using all points considered. The results show a maximal error of $1$ BPM between the true breathing rate and the algorithm's calculated rate, based on experiments on two babies and three adults.

Abstract - Over the past 20 years, digital wireless communications has become an essential technology for many industries, and a primary driver for the electronics industry. Today, computer vision is showing signs of following a similar trajectory. Once used only in low-volume applications such as manufacturing inspection, vision is now becoming an essential technology for a wide range of mass-market devices, from cars to drones to mobile phones. This presentation examines the motivations for incorporating vision into diverse products, presents case studies that illuminate the current state of vision technology in high-volume products, and explores critical challenges to ubiquitous deployment of visual intelligence.
