A novel approach for Freeman Chain Coding with prior modification using cubic interpolation

Transfer of an image through communication link is a very cumbersome job due to large image size and limited bandwidth. For that purpose, image encoding at transmitter side and decoding at receiver side is an essential task. The process of image encoding must be robust for sending accurate boundary of the original image to the receiver. Another important job in image processing is image understanding through recognition of shape, size, area, perimeter and other parameters of an object. One of the well known methods of image encoding is Freeman Chain Coding (FCC). Here in this proposed algorithm we get better result from FCC method with prior modification by cubic interpolation which is useful for high resolution image contour transmission in a coded form through limited bandwidth and in less time. It also provides better result for image understanding and recognition purpose.
