Embodiment Construction
[0026] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] refer to figure 1 , which shows a flow chart of the steps of a method for locating a face provided by an embodiment of the present invention, which may specifically include the following steps:
[0028] Step 101: Obtain the first human face frame and multiple first human face key points in the first frame image in the video stream.
[0029] The embodiments of the present invention can be applied to scenes such as live broadcast and short video that require real-time processing of human faces (such as beautification, face thinning, etc.) and fast positioning of human faces, such as xx live broadcast, xx short video, etc.
[0030] A video stream refers to video stream data collected in real time during live broadcast or vide...

The invention provides a face positioning method and device, terminal equipment and a storage medium. The method comprises the steps of obtaining a first face frame and a plurality of first face key points in a first frame image in a video stream; obtaining each first coordinate of each first face key point in an image coordinate system corresponding to the first frame of image; carrying out tracking processing on each first face key point to obtain a tracking processing result; determining each second face key point corresponding to each first face key point in a second frame image and a second coordinate corresponding to each second face key point according to the tracking processing result and each first coordinate; wherein the first frame of image is a previous frame of image of the second frame of image; and determining a second face frame corresponding to the first face frame in the second frame image according to the second coordinates. According to the invention, the time required by face key point positioning can be reduced, and the requirement of face positioning real-time processing can be met.
Description
technical field [0001] The present invention relates to the technical field of video processing, in particular to a face positioning method, device, terminal equipment and storage medium. Background technique [0002] With the rapid development of the field of live broadcast and short video, there are demands for face beautification, face thinning and virtual wear on mobile terminals. It is divided into two parts: obtaining the face area in the video stream and locating the key points of the face. [0003] In the prior art solutions, the above two parts are usually processed separately, and the face area is acquired by frame-by-frame detection or tracking of the face area, and then the key points are located in the face frame. Most of the face detection algorithms are based on convolutional neural networks. It is too time-consuming to perform face detection and key point positioning on each frame of image in the video stream, and cannot meet the needs of real-time processin...
