Abstract
A system for analyzing images represented by a plurality of raster scan lines of pixel values employs at least one neighborhood transformation stage. The stage includes a processor portion for analyzing windows of neighboring pixel values and providing a transformation output as a function of the pixel values contained in the window. A random access memory (RAM) repetitively stores a given plurality of successive pixel scan lines fed to the stage. Selected pixel values from the RAM are loaded into the processor portion so as to sequentially access the neighborhood windows for analysis. The RAM serves as a recirculating line storage device for accommodating different raster scan line lengths.
