Perceptual based SAO rate-distortion optimization method with a simplified JND model for H.265/HEVC

作者：

Highlights：

• The human visual characteristic is first introduced into SAO optimization process.

• A new simplified just noticeable distortion (JND) model is proposed.

• A modified Sobel operator is proposed.

• The proposed method can achieve better image subjective quality.
