Target face picture extraction method and device and terminal equipment

Abstract

The invention is applicable to the technical field of image processing, and provides a target face image extraction method and device and terminal equipment, and the target face image extraction method comprises the steps: obtaining a video image comprising a plurality of faces, wherein the video image comprises a plurality of frames of images; performing face detection on the multiple frames of images, and determining a target area corresponding to a target face in each frame of image; wherein the target human face is one or more human faces in the plurality of human faces; determining a motion track corresponding to the target face based on the target area of the target face in each frame of image; wherein the target area in each frame of image corresponds to one face picture; and basedon the posture of the target face in each frame of image, determining at least one target face image in a plurality of face images corresponding to the motion trail. According to the method and the device, the face picture with high quality and low repetition rate can be captured for face recognition, so that the face recognition efficiency can be improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a method, device and terminal equipment for extracting a target face picture.
