The present invention provides a multi-person image scoring method, system, device and storage medium based on face analysis. The method includes: acquiring multi-person images, and using a face detection algorithm to detect the position and size of each face in the multi-person image and angle; use the face quality scoring algorithm to calculate the face quality score of each face in the multi-person image; calculate the face weight of each face according to the position, size and face quality score of each face in the multi-person image; combine The face weight and face quality score of each face is used to calculate the face comprehensive score in the multi-person image; the light source consistency score of the multi-person image is calculated by using the light source consistency analysis algorithm; the formation analysis algorithm is used to calculate the team image of the multi-person image Shape score; calculate the total score of multi-person images based on the face comprehensive score, light source consistency score and formation score. The present invention can not only detect the quality of the photographed multi-person images by using the final scoring of the multi-person images, but also provide assistance to improve the photographing quality when the multi-person photos are taken together.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a multi-person image scoring method, system, device and storage medium based on face analysis. Background technique [0002] In the process of taking a group photo with multiple people, it is difficult to control the lighting, expression, and posture of each person, and some people's faces often reflect light or have shadows, eyes closed, weird expressions, and head turning. Human eyes are needed to judge the image quality. [0003] However, using human eyes to judge involves human subjective factors, and the difficulty of judgment increases as the number of people taking pictures together in the photo increases. In addition, compared with single-face images, comprehensive scoring is performed from the aspects of image blur, face occlusion, and face rotation angle, while multi-face images lack an effective scoring method. Contents of the invention [0004] In...
