Method of image visual quality evaluation based on human visual characteristics

Abstract

To better evaluate image quality,the authors proposed a top-down no-reference image objective quality evaluation method based on the research of human visual model and human visual characteristics.The new method divided the target image into segments and calculated every segment in different color channel,then output the average visual property values.It made evaluation model not only be consistent with the advantage of objective quality assessment,but also took into account the human visual experience.It was consistent with the objectivity and subjectivity of human eyes.The validated results of image subjective evaluation on database of TEXAS University of United States prove that the proposed method gets better consistency with subjective assessment.
