Method and device for realizing portrait video dynamic breast enlarging, crotch beautifying and swan neck effect

Abstract

The invention relates to a method and a device for realizing dynamic breast enlarging, crotch beautifying and swan neck effects of a portrait video; the method comprises the steps: obtaining a video, carrying out the video decoding of the video, and obtaining a frame image of each frame of the video; inputting the frame image into a pre-constructed neural network model, and processing the frame image according to an output result of the neural network model to obtain an optimized image; enabling the neural network model to receive the frame image and outputting the data when the human body key point data is positioned in the frame image; and encoding the optimized image by using a video encoder to obtain video encoding data, synthesizing the video encoding data by using a video synthesizer, and outputting an optimized video. A video frame image is obtained by decoding an input video. The human body key point information in the video frame image is positioned through the neural network model. The human body key point information is combined with an optimization algorithm to achieve the effect of beautifying the figure in the video, and finally the video subjected to figure optimization is exported.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and a device for realizing the effect of dynamic breast enlargement, crotch enhancement and swan neck enhancement in a portrait video. Background technique [0002] Due to the increasingly widespread application of mobile terminals, the way for users to obtain portrait videos is becoming more and more convenient. Users have higher and higher requirements for editing portrait videos. Optimize the body of the portrait in the video to enhance the beauty of the video. However, in the existing video shooting, editing and beautifying applications of this kind, only the key points of the body can be identified in real time during real-time shooting to make adjustments such as thin waist and long legs to achieve the effect of roughly beautifying the body, which cannot be done. Fine adjustment of each part. On the other hand, for videos shot by video record...
