Abstract
An intermediate level vision system that utilises grey scale levels (typically 8 bits or 256 levels in our case) has been implemented which locates and links intensity discontinuities in a digitized image to subpixel precision. The discontinuities are located and localised by utilizing the zero crossings in the laterally inhibited image of the digitized picture.Keywords
