Texture synthesis using a growth model

A systematic method of gray tone texture generation is presented. The procedure is composed of two phases. The first phase is to generate a set of images having characteristic pattern structures. Called mother images, these are synthesized by repetitive applications of seed distribution operations, skeleton growth operations, and muscle growth operations. The second phase is to synthesize a set of gray tone textures from a mother image by applying specific probabilistie transformations which convert numbers in the mother image to gray tone values.
