Abstract
This paper studies the methods of image digital watermarking based on wavelet transform. Firstly, the characteristics of image digital watermarking as well as its processing procedure are introduced. On this basis, the discrete wavelet transform (DWT) is selected to achieve the embedding and distilling of image digital watermarking. Simulation test proves that this algorithm can embed or distill digital watermark effectively. Meanwhile it also proves that this watermark has better abilities of hiding and anti-interference. This method results in significant amount of computational savings as well.
