Abstract

The embodiment of the present application provides a facial image scoring method and a camera. The method comprises: acquiring a facial image to be rated; sending the facial image to be rated to a pre-trained neural network, and scoring the facial image to be rated by the neural network according to network parameters to obtain a reference score; extracting the facial image to be rated Each key point in the face area; according to the distance between each key point and the corresponding relationship between the preset distance and the size score, determine the size score of the face area in the facial image to be rated; according to the reference score and size score, determine the The final score of the face image to be scored. Applying the solutions provided by the embodiments of the present application can improve the rationality of scoring facial images.

Description

technical field [0001] The present application relates to the technical field of image scoring, in particular to a facial image scoring method and a camera. Background technique [0002] With the development of computer vision technology, face recognition technology has been widely used in many fields. For example, it is applied in areas such as companies, homes, banks, etc. In the application, the camera can capture face images at set time intervals and save the face images. For the same person, many face images will be captured within a period of time. If each face image is saved, a lot of resources of the device will be occupied. Therefore, the best image is generally selected from multiple face images for preservation. [0003] When selecting the best image from multiple face images, each face image can usually be scored, and the face image with the highest score is selected as the best image. When scoring each face image, it is possible to detect information such as...
