Reconstruction of Binary and Gray-Scale Images from Mid-crack Code Descriptions

Abstract The chain code is a widely-used description for a contour image. Recently, a mid-crack code algorithm has been proposed as another more precise method for image representation. A simple and fast algorithm for the restoration of binary images based on mid-crack codes description is presented in this paper. The algorithm developed has the advantages of speed, simplicity, and less storage. The algorithm also can be applied to gray-scale images with multiple regions efficiently.
