Generation of linguistic filter structures for image enhancement

This abstract describes ongoing research in the application of formal language theory to the problem of generating two-dimensional digital filter structures for image enhancement. This work is related to the development of an interactive enhancement language for use in teleoperator systems. The approach presently being followed consists of altering the Fourier transform of an image by means of a two-dimensional filter structure. The inverse transform then yields an image which has been enhanced in some sense. This paper describes typical filter primitives and the grammars used to generate appropriate filters. The problem of generating pseudo-color linguistic structures is also discussed.
