Code Transformation Algorithms for Two Breadth-First Linear Quadtrees

In this paper, the code transformation algorithms between the fixed binary linear quadtree scheme (FBLQ)and the constant bit-length linear quadtree scheme(CBLQ) are proposed. There exists no code transformation algorithm between FBLQ and CBLQ. To solve this problem that when one receives a FBLQ or CBLQ code and does not have the corresponding decoding program, with our new code transformation algorithms at hand, she/he can transform the received code into CBLQ or FBLQ code that she/he can handle.The code transformation algorithms can also be used to reduce the load an image lays on the system by transforming it from a higher complexity code to a lower one.
