However, manually analyzing retinal vessels is time-consuming, subjective, and error-prone. In this talk, Rolando Estrada will present an automatic, graph-theoretic framework for retinal vessel analysis, with which he will address two fundamental problems: (1) estimating the 3D vascular topology from a single 2D fundus image and (2) automatically classifying retinal arteries and veins. His framework regularizes these inverse problems via a generative tree-growth model and expert, domain-specific features. He will show how to efficiently maximize his model through heuristic search and present state-of-the-art experimental results which confirm the effectiveness of the approach. He will also discuss future research directions, which include: estimating additional vascular properties (e.g., tortuosity or layer location), exploring other imaging domains, and leveraging deep learning techniques.<\/span><\/p>\n<p class=\"p1\"><span class=\"s1\"><b>Speaker Bio:<\/b><\/span><span class=\"s2\"> Rolando Estrada holds a Ph.D. in computer science and a M.S. in biomedical engineering from Duke University; he carried out postdoctoral research in ophthalmology at the Duke University Medical Center. His research spans computer vision, medical imaging, machine\u00a0<\/span><span class=\"s2\">learning, and neuroscience. Some of his current and recent projects include: automating retinal vessel analysis and classification; developing novel segmentation and registration algorithms for fundus, MRI, CT, and OCT images; investigating EEG-based interventions to improve memory consolidation; and exploring novel deep learning methods based on reinforcement and transfer learning.<\/span><\/p>\n<p class=\"p1\">\n","protected":false},"excerpt":{"rendered":"<p>Speaker:\u00a0 Rolando Estrada, PhD, Research Scientist, Teledyne Scientific and Imaging Date: Monday, February 27, 2017 Time: 4:15pm Place:\u00a0 FGH, Room 136 Title:\u00a0 Automating Retinal Vessel Analysis: Topology Estimation and Artery-Vein Classification Abstract:\u00a0 The retinal vasculature is clinically important, not only for diagnosing ocular diseases, including diabetic retinopathy and glaucoma, but also for monitoring conditions with&#8230;<\/p>\n","protected":false},"author":5,"featured_media":5244,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"spay_email":"","jetpack_publicize_message":"","jetpack_is_tweetstorm":false,"jetpack_publicize_feature_enabled":true,"_links_to":"","_links_to_target":""},"categories":[12],"tags":[231],"acf":[],"jetpack_featured_media_url":"https:\/\/cdn.vanderbilt.edu\/vu-URL\/wp-content\/uploads\/sites\/193\/2019\/03\/19170925\/Picture1.jpg","jetpack_publicize_connections":[],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p98pzF-1my","_links":{"self":[{"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/posts\/5242"}],"collection":[{"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/comments?post=5242"}],"version-history":[{"count":3,"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/posts\/5242\/revisions"}],"predecessor-version":[{"id":5246,"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/posts\/5242\/revisions\/5246"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/media\/5244"}],"wp:attachment":[{"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/media?parent=5242"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/categories?post=5242"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vanderbilt.edu\/vise\/wp-json\/wp\/v2\/tags?post=5242"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
