  • New paper accepted for publication in Journal of Vision

    J. Orlowski, C. Beissel, F. Rohn, Y. Adato, H. Wagner, and O. Ben-Shahar, Visual pop-out in barn owls: Human-like behavior in the avian brain.

  • Agrovision

    Modern agriculture and horticulture are often labor intensive. At the same time, while wages are on the rise, the availability of a skilled workforce that is willing to perform the repetitive tasks in the harsh environmental conditions of a greenhouse, orchard or a field, is decreasing rapidly. Interestingly enough, however, the current state of the […]

  • Sweeper project launched

    Representative from the iCVL participated in the kickoff meeting of the Horizon 2020 project Sweeper. Meeting held in Wageningen, the Netherlands and included 6 groups from European academia and industry. Please see the Sweeper Project web site for more information.

  • New Grant awarded by the Horizon 2020 ICT program

    Sweet Pepper Harvesting Robot (SWEEPER). Project involving 6 European groups and ~4M Euros. Start date expected in February 2015.

  • Contextual Emergence of Object Saliency

    Introduction Visual context is used in different forms for saliency computation. While its use in saliency models for fixations prediction is often reasoned, this is less so the case for approaches that aim to compute saliency at the object level.We argue that the types of context employed by these methods lack clear justification and may […]

  • Symmetric Object Detection and Pose Estimation in 3D

    Welcome Knowing the poses of objects before their detection or classification has been shown to improve the results of object detectors. However, a robust and fine estimation of object poses is still challenging. To do just that, we suggest to employ the mirror symmetry of objects, providing a part of the pose information. In our […]

  • Hyperspectral Imaging from low cost sensors

    In contrast to most artificial and biological optical sensors, hyperspectral imaging systems allows us to accurately recover the full spectral profile of each point in the observed scene. This rich spectral information has been explored and exploited in many fields such as astronomy, biology, chemistry, agriculture, geology, environmental studies and in a wide variety of […]

    Congratulations to Boaz Arad for receiving the interdisciplinary research scholarship from the Zlotowski Center for Neuroscience


November 2012

  • New paper accepted to Journal of Vision

    I. Kadar and O. Ben-Shahar, A perceptual paradigm and psychophysical evidence for hierarchy in scene gist processing.

  • Free Boundary Conditions Active Contours

    Welcome to our Free Boundary Conditions Open Active Contours (FBCOAC) project page! Here you may find various demos and download all project related materials such as the paper, supplementary materials, and the MATLAB code which allows you to experiment with the free boundary conditions active contour model using convinient GUI. Active contours with free boundary […]

  • The OwlCam Project

  • Visual behavior, anatomy, and physiology in the archerfish

    The archer fish (Toxotes chatareus) exhibits unique visual behavior in that it is able to aim at and shoot down with a squirt of water insects resting on the foliage above water level and then feed on them. This extreme behavior requires excellent visual acuity, learning, and tight synchronization between the visual system and body […]

  • The Perceptual Singularities without Feature Gradient project

    Under Construction

  • Curve completion in the tangent bundle

    Curve Completion – What is it all about The ease of seeing hides many complexities. A fundamental problem is the one of fragmentation as we are able to perceive objects although they are optically incomplete or fragmented, in particular due to occlusion. A central mechanism that addresses this difficulty in biological and artificial visual systems […]

  • Polar representation of motion and implications for optical flow

    Motivation Classical and contemporary optical flow algorithms aim to estimate image motion fields (a.k.a. optical flows) that emerge from scenes with rigid or articulated objects, i.e., motion fields with roughly piecewise smooth motions, and no turbulences or complicated singularities (and most often, just piecewise constant velocity). However, the variety of motions exhibited by natural or […]

  • Shape from Specular Flow

      Motivation A central problem in computer vision is the estimation of 3D shape from images. Much work has been devoted to this problem in the context of lambertian or mostly diffused objects. But what happens when the object is specular? Indeed, an image of a purely specular (mirror-like) object is just a distortion of […]

  • Scene Gist Recognition from Perceptual Relations

    Welcome Humans has this remarkable ability to comprehend visual scenes rapidly and accurately. Whether we quickly change television channels, browse photo albums, or simply trying to cross the road, our visual system is working with superb efficiency, accuracy, and speed to extract the meaning of each scene. Examine the rapid sequence of scenes on the […]

  • Computational Jigsaw Puzzle Solving

    Welcome It is quite likely that you, the reader, have tried to solve jigsaw puzzles before. Could computers do the same once given the bag of pieces? This problem has been studied progressively (though sporadically) since the 1960’s, but only recently could algorithms began to handle problems of reasonable size at reasonable success rate. In […]

  • New paper accepted to Journal of Vision

    A. Ben-Simon, O. Ben-Shahar, G. Vasserman, M. Ben-Tov, and R. Segev, Visual Acuity in the Archer Fish: Behavior, Anatomy and Neurophysiology.
