Texture segmentation and region classification by orthogonal decomposition of co-occurrence matrices

Techniques are presented for determining the periodicity and scale of texture; this information is used to define an adaptive transform based on edge co-occurrence matrices for segmenting textured regions. The texture of the region is characterised by an orthogonal decomposition of the co-occurrence matrix using 2-dimensional discrete Hermite functions. The coefficients of this decomposition provide a low order feature vector which can be used for texture classification
