摘要

A novel image watermarking algorithm based on discrete wavelet transformation (DWT) and chaotic is proposed block the carrier image, scrambling and block the watermark image. First, randomly selected a block of carrier image decomposed by means of the wavelet transform, embed a piece of watermark image into low frequency coefficients of a piece of carrier image. According to the characteristics of the binary watermark image and set the adjustment factor.
