Video special effect processing method and device, terminal and storage medium

Abstract

The invention discloses a video special effect processing method and device, a terminal and a storage medium, and belongs to the technical field of video processing. The method comprises the followingsteps: 1, ; the method comprises the steps of obtaining a plurality of first face key points of a first image of a video, determining image features of the plurality of first face key points, determining a plurality of second face key points matched with the image features in a plurality of frames of second images, performing special effect processing on the plurality of frames of images based onthe plurality of face key points, and generating a target video based on the plurality of frames of images after special effect processing. According to the embodiment of the invention, the method comprises the steps: carrying out the processing, a plurality of first face key points of a first image are manually calibrated; respectively matching the multiple frames of second images with the imagefeatures of the first face key points; according to the invention, automatic recognition of the face key points of multiple frames of second images can be realized, special effect processing is carried out on the image based on the face key points of each frame of image, special effect processing of the video is realized, a third-party face recognition platform is not needed, and the problem thatthe frame rate is reduced due to too long time consumption is avoided.

Description

Technical field [0001] This application relates to the technical field of video processing, and in particular to a video special effect processing method, device, terminal and storage medium. Background technique [0002] With the rapid development of video processing technology, special effects processing on faces in videos has been widely used. In order to increase the fun of the video, users can perform special effects processing on the faces in the video, such as adding props stickers, emoticons, etc., so as to achieve special effects when playing the video. [0003] At present, the special effects processing method of video is usually: when recording a video, call a third-party face recognition platform for face recognition, identify the key points of the face in the video, and perform real-time detection and tracking of the key points of the face , And then perform special effects processing on the detected and tracked faces, so as to achieve special effects when playing vid...

Problems solved by technology

[0004] However, face recognition through a third-party face recognition platform requires a large amount of data interaction with the third-party face recognition platform, such as sending videos, receiving recognition results, etc., and the third-party face recognition platform also needs to process video It takes a long time to perform recognition to obtain the above recognition results. During video recording, special effect delays and video freezes may occur, which reduces the video frame rate of the video.
