The object is segmented into parts by grouping parallel traces obtained from the ranging system. Making use of the property of generalized translational invariance, the parts are described in terms of generalized cylinders, consisting of a space curve, or axis, and a circular cross section function on this axis. DESCRIPTIVE PHRASES: Computer vision, three-dimensional imaging, recognition of curved objects.","doi":null,"url":"https://ijcai.org/proceedings/1973/78","pdf":"https://ijcai.org/proceedings/1973/0078.pdf","markdown":"https://ijcai.org/proceedings/1973/78.md","bibtex":"https://ijcai.org/proceedings/1973/bibtex/78","volume":{"slug":"1973","title":"Proceedings of the Third International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1973","url":"https://ijcai.org/proceedings/1973/","year":1973,"location":"Stanford, California, USA","dates":"20-23 August 1973","editors":"Nils J.
