The Workshop on Geometrical Modeling and Invariants for Computer Vision was held in Xi'an, China, the 27, 28, 30 April 1995. Exciting new developments were presented and the text of the communications published by Xidian University Press, Xi'an (ISBN 7-5606-0383-1). There are 60 papers included in the proceedings. The papers are edited in five sections: Curved 3D Objects, Image Geometry and Algebra, 3D Projective Invariants, 3D Reconstruction and Robots, and Shape Invariants (see below for the table of content). The proceedings consists of 404 pages with a softcover. Proceedings can be obtained by ordering (only this year) from Daniele Herzog, Lifia-Inria, 46 av.
