Abstract

The present application relates to a double-frame face tracking method and system based on feature extraction, wherein the method includes: obtaining the face position coordinates in the first frame image through a face detection module; Intercept the first target image, and perform feature extraction on the first target image through the face feature extraction model to obtain the first facial features; obtain the height information and width information of the first frame image, and use the height information, width information and face position coordinates Predict the coordinates of the human face area in the subsequent frame; intercept the second target image on the subsequent frame image according to the coordinates of the facial area in the subsequent frame; input the first facial features and the second target image into the double-frame face tracking model, and pass the double-frame human The face tracking model acquires the face position coordinates of the second target image. This application solves the problem of the slow response speed of the access control equipment caused by the large calculation amount of the face tracking algorithm in the related art, reduces the calculation amount in the process of face tracking, and improves the response speed.

Description

technical field [0001] This application relates to the field of face recognition and tracking, in particular to a feature extraction-based two-frame face tracking method and system. Background technique [0002] With the maturing of algorithms related to AI products, access control equipment based on face detection technology has also been widely used. Among them, due to the large amount of calculation of the face detection algorithm model and the high calling frequency, and the conventional embedded access control equipment generally does not have strong computing power, if the face detection algorithm model is called frequently for a long time, the access control equipment There will be problems of slow response and high power consumption. [0003] In related technologies, traditional face tracking detection methods include meanshift algorithm, Kalman filter, particle filter, optical flow method, csk (Exploiting the Circulant Structure of Tracking-by-detection with Kernel...
