... is called reflected Gray code (RGC). This code is easy to generate with the following recursive construction: Start with the two 1-bit codes (0, 1). Construct two sets of 2-bit codes by duplicating (0, ... with the concepts of successor and predecessor. An integer N has both a successor N + 1 and a predecessor N − 1. Cantor has shown that the rational numbers are countable; each can be associated ... DCT is therefore done by (1) computing the DCT coefficients of the pixels, (2) quantizing the coefficients, and (3) encoding them with variable-length codes or arithmetic coding. The small coefficients...
