Abstract:
The invention relates to a system and method of identifying an edge of an object in an image. The method comprises: identifying a segment of the image and a central pixel in the segment; identifying a set of mini-vectors as possible edges for the central pixel, utilizing a calculated gradient figure for the center pixel; and producing a reduced set of mini-vectors from the set of mini-vectors by removing mini-vectors that do not generate a continuous edge with an adjacent edge in an adjacent segment in the image.
