A readable watermark with size of 256 bit is adaptively embedded in the Discrete Fourier Transform(DFT) domain in accordance with the conceal quality of HVS. Especially, the predistortion compensation method is used to reduce image distortion generated by image normalization.
根据人眼视觉系统掩蔽特性将一个大小为256 bit的可读水印自适应地嵌入到重要区域的离散傅里叶变换(DFT)域内,同时采用预失真补偿策略弥补图像归一化误差较大的缺陷。
