SIGMA consists of three experts: Geometrie Reasoning Expert (GRE) for spatial reasoning, Model Selection Expert (MSE) for appearance model selection, and Low Level Vision Expert (LLVE) for knowledge-based picture processing. This paper mainly describes the control mechanism f01· the spatial reasoning by GRE, where bottom-up and top-down analyses are integrated into a unified reasoning process.","doi":null,"url":"https://ijcai.org/proceedings/1985/183","pdf":"https://ijcai.org/proceedings/1985/0183.pdf","markdown":"https://ijcai.org/proceedings/1985/183.md","bibtex":"https://ijcai.org/proceedings/1985/bibtex/183","volume":{"slug":"1985","title":"Proceedings of the Ninth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1985","url":"https://ijcai.org/proceedings/1985/","year":1985,"location":"Los Angeles, California, USA","dates":"","editors":"Aravind Joshi","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Perception","track":"Perception","number":183,"pages":{"first":908,"last":914},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
