| Abstract: | The article puts forward a kind of digital watermark algorithm based on wavelet transform that takes the static color image as research object and combines with human visual system model.This algorithm makes a selection to embed watermark in lowest frequency band of origin image wavelet transform,and it can improve the Robust and invisibility.The experimental result shows that this algorithm has strong Robust to the image attack. |
