Neighborhood transformation logic circuitry for an image analyzer system

摘要

An image analyzer system employs one or more neighborhood transformation stages. The stage operates to access groups of neighboring pixels in an image matrix, analyzes them and generates a transformation output as a result of the analysis. The stage includes a logic circuit which is programmable from a central controller. In the preferred embodiment, each pixel in the neighborhood is analyzed by the logic circuit and temporarily stored until other pixels in the group have been analyzed. The combination of analyzed pixel values form the basis for generating the transformation output for the stage. Preferably, the logic circuit is designed to perform both two dimensional and three dimensional image analyses.
