A Novel Watermarking Algorithm Based on Feature Tree Quantization
一种基于小波域特征树量化的数字水印算法*

The feature points in the lowest approximation of the original image are extracted with the scale interaction model for feature detection and the feature tree is created corresponding to these feature points. Then the binary watermark bits are embedded by feature tree quantization. The watermark are robust to many processing such as JPEG, JPEG 2000 and Gaussian noise because the watermark bits are inserted into the features of image.
