| Abstract: | Utilizing Image Retrieval Based on Tamura and Texture Features by analyzing Tamura texture feature of original video source,we extract some frame with max maximum texture features to embed watermarking.Watermark Embedding Algorithm is assisted by wavelet transform.A simulation case shows that the method can efficiently resist watermarking attacks such as Gauss,possion,cropping.And this method shows a good robust to video compression and has a significance of guidance to protect the copyright of video. |

| Keywords: | Content-based image retrieval texture features video watermarking high compress robustness |
