Abstract
Two watermark modification methods – a lossless method and a lossy method – and a GA training procedure for improving the performance of general watermarking schemes are introduced in this chapter. These methods improve the imperceptibility and embedding capacity by modifying and compressing the original watermark according to the block table given and the indices assigned. Also, by introducing the GA training procedure, a better way to assign the indices according to the signal of the cover image can be found. This therefore provides better imperceptibility.
