Abstract

The invention provides an image quality evaluation method and device, a terminal and a computer readable storage medium, and the method comprises the steps: carrying out the contrast adjustment of a to-be-evaluated image, and obtaining an image sequence which comprises a plurality of preprocessed images with different contrasts; respectively extracting feature information of the plurality of preprocessed images; and determining a quality evaluation value of the to-be-evaluated image based on the difference of the feature information corresponding to the plurality of preprocessed images. According to the method and the device, the contrast adjustment processing is performed on the to-be-evaluated image to obtain the plurality of preprocessed images with different contrast, the feature information of the plurality of preprocessed images is extracted, the dispersion degree of the image sequence is measured according to the difference between the feature information of the plurality of preprocessed images and the feature information of the processed images, and then the quality of the to-be-evaluated image is scored. The quality of the to-be-evaluated image can be quantified, so that the purpose of effectively distinguishing the quality of the contrast distortion image can be achieved, and meanwhile, the range of applicable scenes can be expanded.

Description

technical field [0001] The present invention relates to the technical field of image quality assessment, in particular to an image quality assessment method, device, terminal and computer-readable storage medium. Background technique [0002] Image contrast distortion is a very common type of image distortion, which can significantly affect the acquisition of effective information in contrast-distorted images by human eyes or computers. At the same time, with the continuous development of modern technology, image data is showing an exponential growth trend, which contains more images with contrast distortion. Therefore, in order to effectively distinguish the quality of contrast-distorted images and screen out high-quality images that can effectively obtain information, it is necessary to provide an effective reference for human eyes or computers by contrast image quality assessment methods. Contents of the invention [0003] The technical problem mainly solved by the pre...
