Abstract

The invention relates to a face image quality evaluation method and device, computer equipment and a storage medium and relates to the technical field of image processing. The method comprises the following steps of acquiring a target face image; obtaining a similarity distribution distance of the target face image; wherein the similarity distribution distance comprises the distribution distance between the similarity distribution of the same person and the similarity distribution of different persons; and obtaining the image quality of the target face image based on the similarity distribution distance of the target face image. Through the method, automatic acquisition of the image quality can be realized, and meanwhile, the image quality is comprehensively determined from two aspects ofthe same-person similarity and the different-person similarity so that accuracy of acquiring the image quality is improved.

Description

technical field [0001] The embodiment of the present application relates to the technical field of image processing, in particular to a method, device, computer equipment and storage medium for assessing the quality of a human face image. Background technique [0002] Face recognition is widely used in society, and the image quality used for face recognition affects the accuracy of face recognition. Therefore, face image quality assessment plays a very important role in the process of face recognition. [0003] In related technologies, the quality assessment of human face images is realized through the human face image quality assessment model. The purpose of quality assessment model training. [0004] However, in the above-mentioned scheme, since the standard of face image quality is difficult to objectively quantify, the cost of manual labeling is relatively high, resulting in low accuracy of picture quality labeling. Contents of the invention [0005] The embodiment o...
