Research on right quality assessment of image is very meaningful in the image information project

but the objective quality assessment of image cannot always be in accordance with human vision. Any reasonable quality assessment method of image should abide fully by human subjective vision. Due to many factors such as visual psychology

culture background

surrounding environment

different applications and so on

an image can be divided into different regions of interest (ROI) by vision interests. To best advantage of human visual interests

a simplified method for subjective assessment of image is presented to an image with only one ROI in this paper. The degree of visual interest to the ROI of the image is regarded approximately to be an inverse measure of the acreage of the ROI. As the acreage of the ROI is zero

the method will become the objective quality assessment of image

that is to say

the objective quality assessment of image is a specific case of the method in this paper. The experimental results have shown the effectiveness of the proposal scheme. It is in better accordance with human subjective vision.
