Debranjan Sarkar, Pradip Kumar Das · International Journal of Pattern Recognition and Artificial Intelligence · 2000
Linear Quadtree (LQ), Interpolation-Based Binary tree (IBB) and Minimized Boolean Function (MBF) are some of the set-of-codes type of encoding scheme for region representation of binary images. Chain Code (CC) is a well-known technique for boundary representation of such images. It is desirable to develop efficient methods of conversion between the two types of representation schemes. In this paper, we present a generalized algorithm for conversion from set-of-codes type of representation to chain codes. The computational complexity of the algorithm is also discussed.
