Our visual system seems to construct shape from the spatial luminance profile in natural images by a combination of bottom-up feature extraction and top-down expectations about plausible shapes. Although the first stages of feature extraction are fairly well understood in humans, little is known about expectations about plausible shapes.<\/p>\n\n\n\n<p>We hypothesized that expectations about plausible shapes can be described by a probabilistic generative model for planar shapes. We constructed a class of maximum entropy models that captured successively more local features of natural shapes. I will report results from two experiments that attempt to test the ability of these models to describe human expectations about plausible shapes.<\/p>\n","protected":false},"author":2,"featured_media":0,"template":"","meta":{"_acf_changed":false,"footnotes":"","_links_to":"","_links_to_target":""},"cu_event_type":[39],"cu_event_audience":[],"class_list":["post-4874","cu_event","type-cu_event","status-publish","hentry","cu_event_type-colloquium-series"],"acf":{"cu_event_start_date":"2014-03-20T12:00:00","cu_event_end_date":"2014-03-20T13:00:00","cu_event_location_type":"in-person","cu_event_meeting_address_type":"on-campus","cu_building":"DT","cu_event_meeting_room":"2203","cu_event_meeting_address_full":null,"cu_event_virtual_type":"tbd","cu_event_virtual_meeting_link":"","cu_post_thumbnail":false,"cu_event_cost":"","cu_event_registration":"","cu_event_secondary_button":"","cu_event_contact_name":"","cu_event_email":"","cu_event_phone":""},"_links":{"self":[{"href":"https:\/\/carleton.ca\/cognitivescience\/wp-json\/wp\/v2\/cu_event\/4874","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/carleton.ca\/cognitivescience\/wp-json\/wp\/v2\/cu_event"}],"about":[{"href":"https:\/\/carleton.ca\/cognitivescience\/wp-json\/wp\/v2\/types\/cu_event"}],"author":[{"embeddable":true,"href":"https:\/\/carleton.ca\/cognitivescience\/wp-json\/wp\/v2\/users\/2"}],"version-history":[{"count":0,"href":"https:\/\/carleton.ca\/cognitivescience\/wp-json\/wp\/v2\/cu_event\/4874\/revisions"}],"wp:attachment":[{"href":"https:\/\/carleton.ca\/cognitivescience\/wp-json\/wp\/v2\/media?parent=4874"}],"wp:term":[{"taxonomy":"cu_event_type","embeddable":true,"href":"https:\/\/carleton.ca\/cognitivescience\/wp-json\/wp\/v2\/cu_event_type?post=4874"},{"taxonomy":"cu_event_audience","embeddable":true,"href":"https:\/\/carleton.ca\/cognitivescience\/wp-json\/wp\/v2\/cu_event_audience?post=4874"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
