预失真线性补偿 predistortion linearity compensation
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.
