Surface orientation and curvature from differential texture distortion

Proceedings of IEEE International Conference on Computer Vision  
A uni ed di erential geometric framework for estimation of local surface s h a p e and orientation from projective texture distortion is proposed, based on a differential version of the texture stationarity assumption introduced by Malik and Rosenholtz. This framework allows the information content of the gradient of any texture descriptor de ned i n a l o cal coordinate fra m e t o b e characterized in a very compact form. The analysis encompasses both full a ne texture descriptors and the
more » ... riptors and the classical \texture g r adients". For estimation of local surface orientation and curvature f r om uncertain observations of a ne texture distortion, the proposed f r amework allows the dimensionality of the search space t o b e r educed f r om ve to one.
