摘要	The purpose of objectively assessing digital image quality is to obtain the assessment results consistent with human visual perception. Different sensitivity factors of human visual system needs to be considered in the analysis and comparison of image structure in order to obtain the image quality assessment results consistent with human perception. Aiming at the problem that single property of image structure information is too unilateral to describe the comprehensive image structure, a complex number method is used to describe the image structure information. A complex matrix is constructed to describe the image structure information. The complex number is taken as an information combination method; and the local variance component with high human eye sensitivity in the image and the grey scale distribution of the image pixels representing general sensing information are taken as the real part and imagery part, respectively. On this basis, the structure similarity method in non-real number domain and its mathematic model were deeply studied; and the method was used to measure the structure similarity of the complex matrixes of two images; then, the quantitative results were obtained. The LIVE database including 779 distorted images and corresponding fitting function were adopted to verify the complex matrix structure similarity method. The cross-distortion experiment and classification distortion experiment results show that using the proposed complex matrix structure similarity method, the consistency of overall performance with human visual perception is better than that using the state-of-the-art methods, such as MSE, SSIM methods and the new QSSIM method.
