This human visual characteristic is called figure segregation. There is a problem when constructing a cognitive model for figure segregation. That is, one interpretation is selected by most people for some figures, and several interpretations are selected almost equally for other figures. This paper discusses the deciding selection frequency problem. First, a geometrical function is introduced for describing line figures. Next, several Gestalt features (such as symmetry, continuity, etc) are defined using the function. Then, by applying linear multiple regression analysis, the characteristic value of each interpretation is obtained, and the selection frequency is calculated. The results of a psychological experiment show that the model proposed here can simulate human visual perception in figure segregation fairly well.","doi":null,"url":"https://ijcai.org/proceedings/1991/55","pdf":"https://ijcai.org/proceedings/1991/0055.pdf","markdown":"https://ijcai.org/proceedings/1991/55.md","bibtex":"https://ijcai.org/proceedings/1991/bibtex/55","volume":{"slug":"1991","title":"Proceedings of the Twelfth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1991","url":"https://ijcai.org/proceedings/1991/","year":1991,"location":"Sydney, New South Wales, Australia","dates":"24-30 August 1991","editors":"John Mylopoulos and Ray Reiter","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Cognitive Modeling","track":"Cognitive Modeling","number":55,"pages":{"first":366,"last":371},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
