Abstract

The invention discloses a dynamic face recognition method and device based on a video stream.performing sample collection on a training video stream to obtain a face image training sample; sending theface image training samples into a neural network for training, training each face image training sample to obtain a multi-dimensional feature vector, normalizing the multi-dimensional feature vectors, and aggregating K multi-dimensional feature vectors belonging to the same person into one feature vector; and carrying out face recognition on an unknown video stream by utilizing the feature vectors obtained by aggregation. The method is higher in recognition precision, lower in false recognition rate and higher in sample utilization rate, and can improve the false face attack problem.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a method and device for dynamic face recognition based on video streams. Background technique [0002] Face recognition is not only a research hotspot in the field of artificial intelligence, but also has important practical significance in the field of public security. Face recognition technology based on a single frame image usually includes face image sample collection, sample image preprocessing, classifier training and sample recognition and other technical links. Face image sample collection is the cornerstone of face recognition, and its significance is self-evident. The collection of face recognition samples used to be based on images. For example, different people used mobile phones and ordinary cameras to take selfies from different angles under different postures, lighting, expressions, etc., and finally cleaned and sorted the face sample pictures. Sample im...
