Two dimensional /spl theta/-image encoding using Boltzmann machine

A new image transformation, two-dimensional /spl theta/-transformation, is introduced in this paper. The time complexity for a /spl theta/-transformation is very low. Therefore, for a certain class of images, /spl theta/-transformation is a very efficient algorithm for image compression and image indexing. Boltzmann machine can be used to implement a class of /spl theta/-transformation.<
