M.Sc./Ph.D. position on computational visual contour completion
Visual completion is a fundamental perception capacity of human vision and a crucial function for computer vision. Previous computational research in the iCVL has explored the visual contour completion problem in a biologically-inspired and perceptual-consistent fashion, pushing a unique approach that considers the problem not in the image plane but rather in a mathematical space that abstracts the primary visual cortex. Candidate interested in this problem will study both computational aspects and perceptual issues. No special background is needed, but previous experience with tools from analysis, differential equations, differential geometry and numerical analysis, as well as background in visual perception are a plus. For details please contact: Prof. Ohad Ben-Shahar
M.Sc./Ph.D. position on the role of occluder appearance on amodal visual completion
Visual completion is a fundamental perception capacity of human vision and a crucial function for computer vision. Previous perceptual research in the iCVL has explored the effect of various visual cues on the grouping of the inducers, and in this research project we would like to explore the role of the occluder on shape of the computed contour. In particular, we are interested to understand if the shading pattern on the occluder has a role in the perceptual completion outcome. Strong background in Cognitive and Brain sciences is a plus but not a must. For details please contact: Prof. Ohad Ben-Shahar
M.Sc. position on shape completion in neglect patients
Visual completion is a fundamental perceptual capacity taht allows human observers experience whole and coherent objects from visual fragments. Does this capacity depends on the integrity of spatial vision? In this project we will explore this question by testing neglect patients who suffer from a particular spatial deficit related to their spatial visual field. Key in this project is the formulation of special stimuli in which normal and neglect patients are predicted to make different completions . Strong background in Cognitive and Brain sciences is a plus. For details please contact: Prof. Ohad Ben-Shahar
M.Sc./Ph.D. position on eye-movements exploration
Humans execute rapid eye movements between locations well over 100,000 times a day. These movements are an integral part of our visual system, serving in acquiring relevant information, tracking visual targets, and allowing us to operate in our world. Tracking eye-movements and measuring how they change in response to different visual stimuli provide a window into human visual perception. Using either of the ICVL’s head mounted, remote, and portable eye trackers, we are able to explore various aspects of these eye movements and utilize them for the understanding of human behavior for solving specific computational (and occasionally applied) computational tasks in order to incorporate this knowledge into artificial visual systems. For details please contact: Prof. Ohad Ben-Shahar
M.Sc./Ph.D. position on automatic puzzle solving
Automatic solving of jigsaw puzzles has been receiving increasing interest in the computational vision community, and our lab has been pushing the abilities of such algorithms to new fronts. Following this initial success (and a follow up senior project on robotic puzzle solving) we will set to study important (and yet unexplored) extensions of the problem, as well as important applications. Strong background in computer science, algorithms, and computational geometry are a plus. For details please contact: Prof. Ohad Ben-Shahar
M.Sc./Ph.D. position on hyperspectral vision
While color vision allows humans and other primates to see the world in amazing detail, light in the visible spectrum carries more information than just “Red, green and blue”, advanced “Hyperspectral” cameras allow us to explore the would around us in greater detail revealing the hidden colors that lie beyond the capabilities of human vision. Following initial research in the lab that results with new technology for hyperspectral acquisition and reconstruction, several research question emerge about the links between hyperspectral images, color images, and vision. For details please contact: Prof. Ohad Ben-Shahar.
M.Sc./Ph.D. position on scene and object recognition
The ability of humans to recognize and classify both visual scenes and objects is astonishingly rapid and reliable, even when the number of examples experienced from a particular class is very small. Part of this capacity may be assisted by a hierarchical representation of visual classes, reminiscent of artificial datasets like ImageNet, and computational foundations represented as ontologies of the sort our lab has been studying for some time . While ImageNet is based on hierarchy crafted from lexical relationships, a question remains about the perceptual hierarchy that may be innate to the human visual system and how it may have formed during development. In this research project we will explore this question, first using psychophysical and behavioral tools, followed by a computational inquiry that could eventually lead to better recognition algorithms. For details please contact: Prof. Ohad Ben-Shahar
M.Sc./Ph.D. position on deep learning for inverse problems in computer vision
Ill-posed inverse problems in vision (or other domains) are one-to-many problems where the I/O mapping is under-determined. In some very basic sense, the vision problem as a whole is one grand inverse problem. For decades now the computer vision community has been addressing such problems using regularized optimization – a fancy terms to say more constraints are needed to single our certain solutions over others. Could deep learning, the new king in town, do better? In this research project we will explore this topic in depth and tackle some of the most challenging vision problems. For details please contact: Prof. Ohad Ben-Shahar
M.Sc./Ph.D. position on computational vision for the study of animal behavior
Do you care for both computational tools and biological issues? In a long term project with Prof. Ronen Segev from the Life Sciences department we study both behavior and neurophysiology of the archer fish with some visionary applications to futuristic robotics. As part of this project we intend to study and develop fully automatic tools and algorithms for the analysis of the fish behavior, set a fully operational experimental system, and explore the latter in various experiments. For details and how to apply please contact: Prof. Ohad Ben-Shahar.
M.Sc./Ph.D. position on natural image statistics
The statistics of natural images is a source for great advancements in computer vision, as well as in computational modeling of biological and human vision. In this research project we will explore the implications of certain statistical properties of images for image representation, compression, retrieval and search operations, as well as for various methodological advances in visual psychophysics (such as for masking). For details please contact: Prof. Ohad Ben-Shahar
Postdoc position on cognitive assistive robotics
As the elderly population grows, so does the number of elderly patients with restricted mobility, vision, and dexterity. Service robots can help such people perform important tasks safely, allowing them to function independently in their homes many more year. With the enormous societal and economic impact of such robots no accepted, assistive robotics is emerging as a strong discipline that draw much academic and interest (e.g., see recent workshops in IROS 2014, HRI 2014, and ECCV 2014, to name but few). In this spirit we are starting a multidisciplinary projects in assistive robotics involving several PIs and research in of robotics, computer vision, NLP, plannings, and HRI. A seek a postdoctoral researcher with expertise in at least one of these areas to lead the effort. A successful candidate will not only demonstrate excellent research track record but will have hands-on approach, good programming skills, and some knowledge of ROS (or the ability to acquire one quickly).
