A NOISE CLEANER FOR BINARY IMAGES Abstract of the Disclosure The disclosed apparatus operates upon binary signals corresponding to a scanned image. The binary images are stored in a matrix as concentric windows of interconnected rows and columns. The binary signals contained in the rows and columns are summed and logically compared against the sums of binary signals in adjacent windows and if the sums and logical combinations do not exceed pre-selected amounts it is assumed that the binary signals within a particular window are spurious, and means are provided for cleaning these signals from the window. Incrementing the binary images that are stored in the matrix permit the total scanned image to be analyzed.
