Title: The Evolution and Trend of Chain Code Scheme
Authors: Lili Ayu Wulandhari and Habibolah Haron
Abstract: Chain code is an image method representation based on region boundaries. The chain code of region is determined by specifying a starting pixel and the sequence of unit vectors obtained from going either left, right, up, or down in moving from pixel to pixel along the boundary. Chain code is widely used nowadays because it preserves information and allows considerable data reduction. The first approach for representing digital curves using chain code was introduced by Freeman in 1961, and it is known as Freeman Chain Code (FCC). This code follows the contour in clockwise manner and keeps track of the directions as we go from one contour pixel to the next. The codes involve 4–connected and 8– connected paths. Since it was introduced by Freeman, the development of chain code and its application increases rapidly. This paper explains some new chain code concepts and their applications that are be the background of the development of vertex chain code cells algorithm.
