Stereo image objectivity quality evaluation method based on visual perception
InactiveCN102663747AImprove consistencyAccurate judgment basisImage analysisViewpointsScale structure
The invention discloses a stereo image objectivity quality evaluation method based on visual perception. Based on two parts of a left and right viewpoint image quality and depth perception, the left and right viewpoint image quality is used to capture multi-scale structure information so that a difference of a structure similarity of an original and distortion stereo image pair can be effectively reflected. The stereo depth perception is caused by the subtle difference existed in the image seen by left and right eyes of human beings. Through comparing a brightness distortion of original and distortion absolute difference value images, a structure distortion and a sensitivity distortion, a depth perception evaluation value can be acquired. Then, nonlinear fitting is performed on the evaluation values of the two parts so as to obtain a final stereo image quality evaluation index. Because the method combines the specific depth perception characteristic of the stereo image and a objective evaluation model result of the image quality loss characteristic, the quality of the stereo image and the depth perception can be reflected. Therefore, the evaluation result can objectively reflect stereo image processing or influence of a compression algorithm on stereo image quality change.
