An image subjective quality evaluation model based on structural similaity

Image quality evaluation standard of information hiding algorithm mainly relied on the traditional standard such as peak signal to noise ratio (PSNR), but PSNR does not meet people´s subjective assessment. So it is necessary to set up the objective evaluation criteria with subjective uniformity for information hiding algorithm. In this paper, an image subjective quality evaluation model is proposed by structure and hue similarity (SHSIM) with human visual system (HVS), the corresponding relation between ITU-R quality and impairment scales model and objective assessment by SHSIM is set up from these three aspects as structure, color space and human visual system. The experimental results show that the image quality evaluation model has better agreement with the human´s visual judgment.
