We describe and demonstrate a texture region descriptor which is invariant to affine geometric and photometric transformations, and insensitive to the shape of the texture region. It is applicable to texture patches which are locally planar and have stationary statistics. The novelty of the descriptor is that it is based on statistics aggregated over the region, resulting in richer and more stable descriptors than those computed at a point. Two texture matching applications of this descriptordoi:10.1109/iccv.2001.937686 dblp:conf/iccv/SchaffalitzkyZ01 fatcat:vzbctcghhfhtde2syyltiha4l4
