Crop-resistant digital watermarking for image based on structured coding
基于结构化编码的抗剪切图像数字水印

A digital watermarking algorithm based on the accessorial information was proposed to resist cropping attack. The algorithm coded watermark with structured coding, and made the digital watermarking possess the identifying function. The embedding and extracting strategies were designed too. Experimental results show that the algorithm has good extracting effect and the fast speed, and can resist cropping attack and some routine attacks effectively.
