Video watermarking algorithm based on moving target detection and texture complexity
Jiulun Fan · 2013
In order to improve the robustness of the video watermarking,a video watermarking algorithm combining the moving target detection and the texture complexity was proposed.The watermarking was generated by using online clustering of the background subtraction and the background difference to extract the moving target.The generated watermarking was then encrypted by the chaotic encrypted method.Based on the block of the host frame,the encrypted watermarking was embed into a block with larger texture complexity.The experiment results showed that the good robustness for the common attacks was obtained under the premise of ensuring the quality of the video images.
