Abstract
This paper is concerned with accurate detection of the location of boundaries of images projected on a discrete array of photosensors or scanned by a television camera. A model is developed for the detection system and it is shown that proper application of a triangular perturbation signal can yield a linear transfer characteristic between the actual boundary location and the detector output.
