| Abstract: | The watermark project this text put forward is based on Discrete Wavelet Transform(DWT).The relation of the coefficient in the three lowest detail subbed images is used which is not single small wave coefficient to imbed and withdraw watermark.The calculation methods are simple and easily realized.The experiment shows that these methods have good results in most picture processing and have better robustness when it is being attacked. |
