Finally, the marked virtual images are gotten with inverse wavelet transform and a new group of control points is obtained based on the pixel value of the virtual image.
最后,进行小波逆变换,得到含有水印信息的虚拟图像,根据虚拟图像中的象素值就可以得到一组新的控制顶点坐标。
Then, watershed segmentation of the approximation image is computed, and the inverse wavelet transform is used to project this original segmentation up to the higher resolutions.
对近似图像进行分水岭分割,并且用小波逆变换把原始分割结果逐步映射回更高的分辨率层。
