Abstract

The embodiment of the invention discloses a method and apparatus of detecting image quality. The method of detecting image quality includes the steps: acquiring an image to be detected, and the face area information which is obtained by pre-performing face detection on the image to be detected and is used for indicating the face area in the image to be detected; based on the face area information,extracting the face image from the image to be detected; inputting the face image into a pre-trained convolutional neural network to obtain the probability that each pixel point of the face image belongs to the type indicated by each type identifier in a preset type identifier set; inputting the face image into a pre-trained face key point positioning model to obtain the coordinates of each facekey point of the face image; based on the probability and the coordinates, determining the probability that the face image is shielded; and based on the probability of being shielded, determining whether the quality of the face image is qualified. The method of detecting image quality improves the image quality detection efficiency.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a method and device for detecting image quality. Background technique [0002] Face recognition has many application scenarios, such as face payment, face authentication, face beautification and so on. During the face recognition process, if the image quality including the face is unqualified (for example, multiple parts of the face are blocked, etc.), it may lead to recognition errors, or abnormal situations such as system crashes. If the quality of the image including the face is detected first before the face recognition is performed, it is possible to avoid performing a subsequent face recognition process on the image with unqualified quality. This can improve the efficiency of face recognition. Therefore, it is particularly important to perform quality inspection on images including human faces. Contents o...
