Abstract

The invention provides a method, device and system for face characteristic information, and relates to the technical field of image identification. The method comprises the following steps: acquiringa to-be-processed first image frame and a to-be-processed second image frame, wherein the first image frame and the second image frame are at least one pair of continuous image frames in a video stream, the first image frame comprises an estimated face frame and the second image frame comprises a detected face frame; and processing an area identified by the estimated face frame of the first imageframe and an area identified by the detected face frame of the second image frame, and tracking the face characteristic information of the first image frame based on a processing result, wherein the face characteristic information comprises a face frame and / or face characteristic points, so that the technical problem that the accuracy of face identification is more difficult when a complicated face is moved by adopting the face positioning tracking method in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to a method, device and system for tracking facial feature information. Background technique [0002] Face shape point tracking technology refers to tracking one or more faces in a continuous video sequence, and outputting the shape points of faces in each frame in real time. This technology plays a very important role in many occasions, such as locking the activity track of a specific person, driver fatigue detection, processing face frame images in mobile phone beautification, adding props in live video, etc. The accuracy, robustness and efficiency of face tracking are the main concerns of this technology. [0003] In the prior art, this technology is mainly divided into two categories. The first category outputs the face through the iterative calculation of the Supervised Descent Method (SDM) model or the Convolutional Neural Network (CNN). shape points. This...
