Reduced-reference stereoscopic image quality assessment based on view and disparity zero-watermarks

作者：

Highlights：

• View zero-watermarking constructed by judging relation of gradient vectors of two views is used to reflect image structure variation.

• Disparity zero-watermarking constructed by judging relation of disparity is used to reflect stereoscopic perception quality variation.

• RR-SIQA score is obtained by pooling the two kinds of zero-watermark recovering rates.

• Different from normal watermarking, zero-watermarking will not bring any distortion to host image.
