The Research of Semi-Fragile Watermarking Algorithm Based on Dynamic Segmentation
Based on human eye visual characteristics of brightness and texture, a new region segmentation method and quantitative formulas in transform domain were put forward. By dynamic quantization, the transparency of carrier images and the anti-attack capability of watermarking images were improved. And a new kind of adjustment operator was brought up, which adjusted the pixel value after inverse discrete wavelet transform.
