On June 26th, the lab hosted six visitors from Team Homer from the University of Koblenz! Team Homer is part of the Active Vision research group (AGAS, http://agas.uni-koblenz.de) at the Institute of Computational Visualistics of the University of Koblenz-Landau. It was a great day where we heard about their recent victory in the RoboCup @Home […]

Venue: VSS 2018, Florida Paper: Border Ownership Assignment based on Dorsal and Horizontal Modulations Poster: https://osf.io/p4ygh/ Abstract: The face-vase illusion introduced by Rubin (Rubin, 1915) demonstrates how one can switch back and forth between different interpretations by assigning borders to either side of contours in an image. Border ownership assignment is an important step in perception of […]
Read MoreOn April 28th our lab welcomed a number of high school students interested in joining the Lassonde School of Engineering at the Lassonde Open House. The EECS department organized lab tours where students had an opportunity to see exciting research happening here first-hand, as well as hear about undergraduate opportunities at the School. Markus Solbach, […]
Read MoreWe present a Polyhedral Scene Generator system which creates a random scene based on a few user parameters, renders the scene from random view points and creates a dataset containing the renderings and corresponding annotation files. We think that this generator will help to understand how a program could parse a scene if it had […]
Read MoreAbstract Scene Classification has been addressed with numerous techniques in the computer vision literature. However with the increasing size of datasets in the field, it has become difficult to achieve high accuracy in the context of robotics. We overcome this problem and obtain good results through our approach. In our approach, we propose to address […]
Read MorePaper (arXiv): Totally-Looks-Like: How Humans Compare, Compared to Machines Project website. Perceptual judgment of image similarity by humans relies on a rich internal representations ranging from low-level features to high-level concepts, scene properties and even cultural associations. Exist ing methods and datasets attempting to explain perceived similarity use stimuli which arguably do not cover the […]

Read MoreAbstract Indoor Localization is a primary task for social robots. We are particularly interested in how to solve this problem for a mobile robot using primarily vision sensors. This work examines a critical issue related to generalizing approaches for static environments to dynamic ones: (i) it considers how to deal with dynamic users in the […]

Venue: ICCV 2017 Workshop: ACVR, Venice, 2017 Paper: Vision-Based Fallen Person Detection for the Elderly Project link: https://github.com/TsotsosLab/fallen-person-detector Abstract: Falls are serious and costly for elderly people. The Centers for Disease Control and Prevention of the US reports that millions of older people, 65 and older, fall each year at least once. Serious injuries such […]

Venue: CVR 2017, York University Abstract: Experiments on the visual cortex show existence of border ownership (BOS) neurons in V1 and V2. The responses of these neurons not only depend on the orientation of borders, but also on which side of the border the figure is. Neurophysiological studies show that BOS cell responses depend on […]
