This requires eye movements to search for task-relevant features in the scene. This research focuses on search strategies for visual search, specifically human subjects identifying people in cluttered scenes. We present a principled approach to the study of factors that contribute to person search. A novel video database is created that systematically tests how different parts of a person contribute towards eye-movements and person identification. One surprising finding is that a face-centered strategy does not necessarily maximize the person identification performance in human subject trials. Next, a neural network based approach is proposed to model eye movements that further improves upon the current state of the art models. Finally, a new foveated convolutional neural network is presented that leverages multiple fixations and is adaptive to available computational resources to improve the overall recognition rates.</span></p><br><br><p dir="ltr" style="line-height:1.2;margin-top:0pt;margin-bottom:0pt"><span style="font-size:14pt;font-family:"Times New Roman";color:rgb(0,0,0);background-color:transparent;font-weight:700;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre-wrap">BIO:</span></p><p dir="ltr" style="line-height:1.2;margin-top:0pt;margin-bottom:0pt"><span style="font-size:14pt;font-family:"Times New Roman";color:rgb(34,34,34);background-color:rgb(255,255,255);font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre-wrap">Thuyen Ngo is a PhD student at the Department of Electrical and Computer Engineering at the University of California at Santa Barbara. He received the B.Eng. degree in Electrical Engineering from Hanoi University of Technology, Vietnam in 2010 and the M.S. degree also in Electrical Engineering from UC Santa Barbara in 2013. During his PhD at UCSB he interned at perception team at Magic Leap, Inc. His research interests are in human visual perception, machine learning and computer vision.</span></p><br><b style="" id="gmail-docs-internal-guid-87062a51-7fff-6b89-a2f3-858117dc4340"><p dir="ltr" style="line-height:1.2;margin-top:0pt;margin-bottom:0pt;text-align:center"><span style="font-size:12pt;font-family:Cambria;color:rgb(0,0,0);background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre-wrap">Hosted by: Professor B.S.
