With the development of the computer applications and digital technology, the research on watermarking has been the hot topic now. Several methods are introduced about watermarking compression（DFT,DCT,WT） and their performance analyses are given, and the algorithm based on RBF neural network for fast classification is presented for adaptive watermarking embedding, which has higher efficiency and better performance. The watermarking technology for color images is introduced briefly in the end. All the simulation is carried out under the MATLAB 6.5.
