  • In order to improve the consistency of the assessment result of image fusion with that of Human Visual System, the state-of-the-art image fusion assessment methods are deeply analysed, then a new assessment method is proposed in this paper, which is based on the complex number expression for image structure. The gradient information of luminance layer of color image is used to perform the task. When it is used to describe image structure, more human visual system-sensitive information are contain in the corresponding complex matrix. Due to the calculation problem of mutual information, we perform singular value decomposition on the complex matrix, and the singular value vector of each image block is used to construct the new matrix. Results from experiments show that the proposed method gives evaluation of 3.748 5 and 3.722 2 for pyramid and DWT methods. It improves the consistency of assessment results with those of human visual system.
