But vision is full of redundancy and there are several sources of information that if combined can provide unique solutions for a problem. Furthermore, even if a problem as formulated has a unique solution, in most cases it is unstable. Combining information sources in this case leads to robust solutions. In this paper, we combine shading and motion to uniquely recover the light source direction and the shape of the object in view, and we describe how one could combine information sources present in the image in order to achieve uniqueness and robustness of low level visual computations.","doi":null,"url":"https://ijcai.org/proceedings/1987/148","pdf":"https://ijcai.org/proceedings/1987/0148.pdf","markdown":"https://ijcai.org/proceedings/1987/148.md","bibtex":"https://ijcai.org/proceedings/1987/bibtex/148","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":148,"pages":{"first":738,"last":740},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
