Multiresolution feature extraction and selection for texture segmentation [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1989 An approach is described for unsupervised segmentation of textured images. Local texture properties are extracted using local linear transforms that have been optimized for maximal texture discrimination. Local statistics (texture energy measures) are estimated at the output of an equivalent filter bank by means of a nonlinear transformation (absolute ...
