Coordinate logic filters in image processing applications

In this paper we present a number of coordinate logic filters (CL) for image processsing applications. The CL filters execute coordinate logic operations among the pixels of the image. They are very efficient in various image processing applications such as lowpass and highpass filtering, magnification, erosion, dillation, opening, closing, skeletonization, coding, compression as well as edge detection and feature extraction. They may be seen as multi-binary morphological kind of filters and they can be easily and fast implemented using logic circuits or by cellular automata.
