In polyhedral worlds these Features are faces, vertices and edges. Such features Iead naturally to parallel algorithms For building such a scene description from stereo input that are insensitive to noise and oc clusion. This representation can be used For object location, object recognition , and navigation.","doi":null,"url":"https://ijcai.org/proceedings/1985/193","pdf":"https://ijcai.org/proceedings/1985/0193.pdf","markdown":"https://ijcai.org/proceedings/1985/193.md","bibtex":"https://ijcai.org/proceedings/1985/bibtex/193","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":193,"pages":{"first":964,"last":967},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
