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

The invention relates to a facial beautification method and electronic equipment in a real-time video. The facial beautification method comprises the steps of obtaining video frames through a camera; determining skin color areas and non-skin color areas through skin color detection, respectively converting an original image into HSV (Hue-Saturation-Value) and RGB (Red-Green-Blue) spaces, determining areas within a range threshold of limited skin color in the HSV and RGB color spaces as the skin color areas and other areas as the non-skin-color areas, and separating the skin areas from the image; integrally performing pyramid bilateral filtering on the original image, wherein noisy points are considered if a certain threshold is exceeded, and performing medium filtering on the noisy points; directly replacing the skin areas in the original image with images after filtering, and fusing the original image and the images after filtering by the non-skin color areas. By adopting the facial beautification method, the skin color of figures in the video is obviously beautified, the facial beautification efficiency in the real-time video is improved, and the user experience effect is increased.

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...
