A plurality of serial neighborhood transformation pipelines are provided for simultaneously operating on adjacent segments of a partitioned image matrix. Techniques are disclosed for bi-directionally transferring pixel data on the edges of adjoining segments of the image matrix between adjacent processors in a manner which minimizes the number of interconnections therebetween. In such manner a parallel pipeline image processing system can be implemented in integrated circuit form while keeping the number of pins for each stage in the pipeline to a minimum.

A method of analyzing a matrix of pixel values in a serial neighborhood processing system, said system being adapted for sequentially performing a neighborhood transformation on pixel values contained in an array of neighborhood extraction storage devices, said method comprising: partitioning the matrix into a plurality of segments; feeding contiguous segments to adjacent neighborhood transformation stages in a raster scan line format; sensing the relative position of each pixel in the lines fed to each stage; bi-directionally transferring pixels lying on the edges of each segment to adjacent stages over a single connection means before said pixels are loaded into the neighborhood extraction devices for processing; and then, loading neighboring pixel values into said neighborhood extraction devices for processing whereby each stage contains all of the neighboring pixels for performing said neighborhood transformations on the pixels fed to the stage even though some of the neighboring pixels were initially fed to adjacent stages.
