In the image-processing area, accurate evaluation of the processed quality is a key technique. In this paper, a new method using image edge combined with structural similariy,whichtakes the importanceof the edge information to eye perception structure into account, is presented. The objective indexes of experimental images are extracted and calculated， and the experimental data are statistical analysed.The results show that, the new method is better than the structural similarity image quality assessment method and is better fit with the subjective feeling of human visual perception.
