NO-REFERENCE IMAGE QUALITY EVALUATION SYSTEM AND METHOD

摘要

The present invention relates to a no-reference image quality evaluation system and method. The no-reference image quality evaluation system of the present invention comprises a plurality of image information extraction paths, and a non-linear sub-network connected to the image information extraction paths, wherein each of the image information extraction paths comprises a first information extraction network, a second information extraction network and a third information extraction network successively connected to each other; the first information extraction network is used for extracting a basic original structure of an image; the second information extraction network is used for extracting a linear expression of the image; the third information extraction network is used for extracting a statistical independent component of the image; and the non-linear sub-network is used for carrying out feature mapping on the statistical independent component, so as to acquire a final image quality score. By means of implementing the present invention, high consistency between an image quality evaluation result and human visual sensation can be realized.
