Abstract

The invention discloses a face image quality evaluation method, system and device and a medium. The method comprises the steps of acquiring a face image; preprocessing the face images respectively, estimating face postures of the face images and judging attribute types of faces in the face images; and performing joint evaluation on the quality of the face image according to the preprocessing result, the detection result of the face posture and the result of the attribute type of the face. According to the invention, the face image is subjected to joint evaluation by adopting multiple selectable evaluation indexes, so that the image quality can be evaluated more comprehensively and effectively.

Description

technical field [0001] The present application relates to the technical field of face detection, and in particular, to a method, system, device and medium for evaluating the quality of a face image. Background technique [0002] Existing face image quality evaluation methods often combine various attributes of face images to evaluate their quality, including attributes of face pose, occlusion, illumination, and image blur. of multiple attribute values ​​using a rule-based approach to exclude poor-quality face images. The main purpose of face image quality evaluation is to improve the success rate of subsequent face comparison, and reduce the number of face images involved in the comparison. However, the existing face image quality evaluation methods do not consider the relationship between various attributes of the face, and cannot select the required influencing factors for joint evaluation according to a certain place, so it is accurate in the face quality evaluation. Th...
