Embodiment Construction

[0027] Such as figure 1 Shown, a kind of face beautification method in instant video, described method comprises:

[0028] Obtain video frames through the camera;

[0029] Determine the skin color area and non-skin color area through skin color detection, convert the original image into HSV and RGB space respectively, and according to the range threshold of the skin color in the HSV and RGB color spaces, the area within the range is identified as the skin color area, and others is the non-skin area, which separates the skin area from the image;

[0030] Pyramid bilateral filtering is performed on the original image as a whole, that is, the original image is down-sampled at multiple scales, the down-sampled image and the guide map corresponding to each scale are generated, the smallest-scale image is filtered, and the previous scale is deduced through the guide map The picture is iterated layer by layer and finally the filtered image of the original image is obtained. When fi...

Abstract

A face beautification method and electronic device in real-time video, including: acquiring video frames through a camera; determining skin color areas and non-skin color areas through skin color detection, converting original images into HSV and RGB spaces respectively, and defining skin color in Range thresholds on the two color spaces of HSV and RGB. Those within the range are identified as skin color areas, and the others are non-skin color areas. The skin areas are separated from the image. Pyramid bilateral filtering is performed on the original image as a whole. If it is greater than a certain threshold It is considered to be noise, and median filtering is performed on the noise; the skin color area of ​​the original image is directly replaced with the filtered image, and the non-skin color area is merged with the original image and the filtered image at a certain ratio. By adopting the present invention, the skin color of video characters is obviously beautified, which improves the efficiency of beautifying faces in real-time videos and increases the user experience effect.

Description

【Technical field】 [0001] The invention relates to the field of image technology, in particular to a face beautification method and electronic equipment in real-time video. 【Background technique】 [0002] At present, there are many image beauty applications on smart terminals (such as mobile phones and PADs), which are used for image beautification operations: skin resurfacing, acne removal, face thinning, whitening, dark circles removal, eye bag removal, mole removal, acne marks removal, etc. Features. [0003] Most of the existing image beautification technologies are based on static images, and have not been applied to real-time beautification processing of dynamic images of video files. With the popularization of instant video applications on mobile terminals, more and more users realize interaction with others through instant video applications. However, due to the limitations of mobile terminal equipment and the influence of the shooting environment of the interactive...
