Abstract

The invention provides an image quality evaluation method and device, a storage medium and an electronic device, and the method comprises the steps: determining N groups of semantic features of a target image, the N groups of semantic features comprising local features and global features of the target image; determining a group of network parameters corresponding to the target image according to the Nth group of semantic features in the N groups of semantic features; and determining a quality evaluation value of the target image through the group of network parameters and the N groups of semantic features. According to the image quality evaluation method and device, the problem that the accuracy of image quality evaluation is low is solved, and the effect of improving the accuracy of image quality evaluation is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an image quality evaluation method, device, storage medium and electronic device. Background technique [0002] Image Quality Assessment (IQA for short) can be applied in various fields, for example, video surveillance in the security field. Most of the video capture devices are installed outdoors and usually lack maintenance. Due to the influence of weather and other environmental factors, the images captured by the video capture devices may be distorted, degraded or too dark. Evaluating the quality of pictures and selecting high-quality pictures can improve the accuracy of image recognition. [0003] The current image quality assessment methods are generally subjective quality assessment. Subjective quality assessment methods rely on manual implementation, which is time-consuming and labor-intensive in practical applications, and the accuracy of manual assessment with subjec...
