Problems solved by technology

However, objective evaluation methods usually have some problems. The existing single-index image quality objective evaluation methods are likely to lead to the phenomenon of "inconsistency in multi-index evaluation conclusions" due to the differences in the mechanism of each single-index evaluation method and the perspective of the analysis problem. That is, the evaluation results obtained by different evaluation indicators will be contradictory; at the same time, due to the similarity of some indicators in the evaluation algorithm, the obtained evaluation results may also be correlated

Abstract

The present invention relates to the technical field of image evaluation, in particular to an image quality comprehensive evaluation method and system, the method includes: selecting a number of different single-factor image quality evaluation indicators; for each image in at least one image to be evaluated, calculate For each single-factor image quality evaluation index, calculate the value of each single-factor image quality evaluation index for each image; calculate the difference coefficient of each single-factor image quality evaluation index according to the value of each single-factor image quality evaluation index for each image ; According to the difference coefficient of each single-factor image quality evaluation index and each single-factor image quality evaluation index value of each image, the comprehensive quality evaluation value of each image is calculated. The present invention is able to achieve true level of image quality in full objective fan flat.

Description

technical field [0001] The invention relates to the technical field of image evaluation, in particular to a method and system for comprehensive evaluation of image quality. Background technique [0002] Human beings and the natural world are connected through perception, and the most important thing in perception is vision, and most of the information sources corresponding to vision come from images. Image is a vivid description of objective objects, which is more effective and intuitive than other representation methods. High-quality images are very important for human beings to perceive and recognize the outside world. To some extent, image quality determines the adequacy and accuracy of the information obtained. However, in the process of image acquisition, compression, transmission, display, etc., images are easily degraded. Image quality is an important index to compare the advantages and disadvantages of various image processing algorithms and to optimize system para...
