With the improvement of peoples requirement for image quality, image quality evaluation method is also a new study more. At present, the image quality evaluation method can be divided into objective image quality evaluation method and subjective image quality assessment. Subjective evaluation method is closer to the human subjective feelings, but more difficult to implement. In recent years, due to HVS model can well reflected the physiological characteristics of the human eye, so HVS is widely applied to image quality evaluation method. The masking effect of the HVS model is attention by more and more scholars. The main research of this paper is combined with the masking effect and spatial similarity put forward an image quality assessment method. Major research works are as follows: 1. Research the current situation of image quality evaluation method, and summary characteristic of HVS; 2. Study the masking effect and spatial similarity, then summarizes the relevant theoretical knowledge; 3. Combined with the masking effect and spatial similarity put forward the image quality evaluation method based on masking model and spatial similarity, and establish the mathematical model. After repeated experiments and compared with traditional image quality evaluation method, it is proved that this method is more consistent with human subjective sensation.
