Abstract

The invention discloses a face photo quality evaluation method, system and device and a storage medium, and the method comprises the steps: evaluating image quality of a face image to acquire a plurality of preliminary evaluation coefficients; according to the weight of each preliminary evaluation coefficient, weighting each corresponding preliminary evaluation coefficient to obtain a weighted evaluation value of the face image; and performing feature extraction on the face image to obtain a feature evaluation value, and performing final quality evaluation on the image quality of the face image according to the feature evaluation value. The problem that a face recognition system cannot recognize a face image or is wrong in recognition due to the fact that the quality of the face image becomes poor in various actual complex environments is solved, and the recognition rate of face recognition is greatly increased.

Description

technical field

[0001] The present invention relates to the technical field of face recognition, in particular to a method, system, device and storage medium for evaluating the quality of a face photo. Background technique

[0002] Facial Recognition (Facial Recognition) is a computer technology that uses the analysis and comparison of facial feature information of human faces for identity recognition. Face recognition has high practical value due to its advantages of non-contact, basically no cooperation, and strong concealment of operation, and is considered to be a widely used biometric identification technology.

[0003] Face recognition is an important research field in biometric recognition technology. It covers image processing, neural network, psychology, physiology, artificial intelligence, pattern recognition, computer vision and artificial intelligence. The development of the field is of great significance both in theory and in practice. Face recognition technol...
