A method which constructs local cosine bases with K-regular through cosine modulated 2-D perfect reconstruction filter bank is proposed. In this method, orthogonal wavelets with the number of arbitrary division in 2-D can be constructed if the polyphase components of the base lowpass filter have the relation of doubly-complementary and satisfy regular condition.
