Our approach takes into account the representation cost alid quality of the shapes themselves, and balances the geometric requirements against the photometric evidence. This balance is essential for any system using underconstrained or generic feature models. We introduce examples of specific models allowing the actual computation of the terms in the objective function, and show how this framework leads naturally to control param eters that have a clear semantic meaning . We illustrate the properties of our objective functions on synthetic and real images.","doi":null,"url":"https://ijcai.org/proceedings/1989/254","pdf":"https://ijcai.org/proceedings/1989/0254.pdf","markdown":"https://ijcai.org/proceedings/1989/254.md","bibtex":"https://ijcai.org/proceedings/1989/bibtex/254","volume":{"slug":"1989","title":"Proceedings of the Eleventh International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1989","url":"https://ijcai.org/proceedings/1989/","year":1989,"location":"Detroit, Michigan, USA","dates":"August 20-25 1989","editors":"N.
