Paper (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 […]

Abstract 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 […]

Abstract: In this paper we introduce a stereo vision based CNN tracker for a person following robot. The tracker is able to track a human in real time using an online convolutional neural network. Our approach enables the robot to follow a target under challenging situations like occlusions, appearance changes, pose changes, crouching, illumination changes […]

The Interaction of Target-Distractor Similarity and Visual Search Efficiency for Basic Features Authors: Calden Wloka, Sang-Ah Yoo, Rakesh Sengupta, and John K. Tsotsos Abstract: Visual search efficiency is commonly measured by the relationship between subject response time (RT) and display set size. Basic features are visual features for which a singleton target can be found […]

Abstract: Person following behaviour is an important task for social robots. For letting robots to follow a person, we have to track the target in real time without critical failures. There are many situations where the robot will potentially loose tracking in a dynamic environment, e.g. occlusion, illumination, pose-changes, etc. Often, people use a complex […]

J.K. Tsotsos, Y. Kotseruba, and C. Wloka (2016) A cluster of conspicuity representations for eye fixation selection. Society for Neuroscience (SfN) Abstract: A computational explanation of how visual attention, interpretation of visual stimuli, and eye movements combine to produce visual behavior seems elusive. Here, we focus on one component: how selection is accomplished for […]

JAAD is a new dataset (by I. Kotseruba, A. Rasouli, J.K. Tsotsos) for studying joint attention in the context of autonomous driving. It contains an annotated collection of short video clips representing scenes typical for everyday urban driving in various weather conditions. JAAD dataset contains 346 high-resolution video clips (most are 5-10 sec) extracted from […]

Society for Neuroscience (SfN) Abstract: In order to perform everyday visual tasks we store temporary sensory information in visual working memory (VWM). In spite of considerable neurophysiological and psychophysical data, the actual […]
