Feedback type image quality layering method

The invention aims at solving the problem that subjectively interested areas of a user cannot be accurately reflected at the existing JPEG2000 standard and providing a feedback type image quality layering method. The feedback type image quality layering method comprises the steps of 1 analyzing interested areas of original image signals to establish an important index matrix; 2 performing layering according to the important index matrix and encoding and transmitting each layer of matrix information; 3 determining the subjectively interested areas according to feedback information and optimizing the important index matrix. The feedback type image quality layering method integrates with an interested area algorithm and an image edge detection algorithm, quality layering is achieved, and interested areas of images can be also highlighted at low bit rate.
