ABSTRACT:
A method and means for analyzing and labeling picture elements ( pixels) in a raster-scanned image includes utilizing a fixed pixel labeling priority rule that takes into account near-neighbor frame border pixels that are not included in the currently-viewed portion of the image by substituting the inverse of the value of the current image pixel being labeled in place of undefined border pixels outside the viewed image portion.
