Embodiment Construction
[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It should be understood that the specific embodiments described herein are only used to explain the related application, but not to limit the application. In addition, it should be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.
[0028] In recent years, Image Quality Assessment (IQA) has become an important research direction and research hotspot in the field of image processing. Image quality evaluation methods can generally be divided into subjective evaluation methods and objective evaluation methods. Subjective evaluation is mainly based on the subjective scoring of image quality by multiple observers. The commonly used scoring mechanisms are Mean Opinion Score (MOS) or average. Subj...

The embodiment of the invention discloses an image quality evaluation method and device, equipment, a chip and a storage medium. The method comprises the steps of obtaining a to-be-evaluated image and a corresponding true value image; determining a color information difference value and an edge information difference value between the to-be-evaluated image and the true value image; and performing weighted calculation on the color information difference value and the edge information difference value by using a preset weight value to obtain an image quality evaluation result of the to-be-evaluated image. Therefore, according to the technical scheme of the invention, a human eye vision system can be fused into an image quality evaluation system, and the difference between the color information and the edge information is used as an evaluation index, so that the accuracy of an evaluation result can be improved, and the matching degree of the evaluation result and the subjective feeling of human eyes is improved.
Description
technical field [0001] The present application relates to the technical field of image evaluation, and in particular, to an image quality evaluation method, device, device, chip and storage medium. Background technique [0002] Images are the main source for people to obtain information. With the popularization of smart phones, video cameras, digital cameras and other electronic devices, a large number of images are obtained every moment. The rapid development of Internet technology makes the transmission and sharing of these images fast and convenient. In the process of image acquisition, transmission, processing and display, some unavoidable interference factors often lead to the degradation of image quality, such as electronic noise, jitter blur, data loss caused by compression, etc. It is the premise of accurate understanding and better use of images. [0003] Among them, in the current image quality evaluation system, Peak Signal To Noise Ratio (PSNR) and Structural Si...
