In this paper we describe the feature selection algorithms and the relational data structure used for matching. We also present a clustering algorithm that is used to group the tokens into sets of similar tokens. The matching algorithm uses this classification information to plan a matching strategy. The least ambiguous image features are matched first and are used as a 'handle' for constraint propagation. We present two algorithms for feature selection in colour images - a region grower and an interest operator, as well as experimental results for point classification and region classification.","doi":null,"url":"https://ijcai.org/proceedings/1987/151","pdf":"https://ijcai.org/proceedings/1987/0151.pdf","markdown":"https://ijcai.org/proceedings/1987/151.md","bibtex":"https://ijcai.org/proceedings/1987/bibtex/151","volume":{"slug":"1987","title":"Proceedings of the Tenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1987","url":"https://ijcai.org/proceedings/1987/","year":1987,"location":"Milan, Italy","dates":"","editors":"John McDermott","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Perception","track":"Perception","number":151,"pages":{"first":749,"last":750},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
