Abstract

The invention discloses a method and device for determining a face area. The method comprises the following steps that: receiving a positioning request, wherein the positioning request is used for requesting to position a face area in a target picture; through a convolutional neural network, carrying out a face positioning operation on the target picture to obtain a positioning result, wherein the convolutional neural network is used for calling a graphics processor to carry out a convolutional operation on the target picture, and the face positioning operation comprises the convolutional operation; and under a situation that the positioning result is used for showing that the face area is in the presence in the target picture, returning a positioning result. By use of the method, the technical problem of poor face detection instantaneity in a relevant art is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for determining a human face area. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition. [0003] Face detection, as the basis of face recognition, face key point location, face retrieval and other applications, has been widely studied. Face detection is to judge whether there is a face in the image in a certain way from a given image, and if so, give the size and position of the face, such as figure 1 As shown in , the image on the left is detected, the image on the ri...
