Example Embodiment

[0035] The present invention will be further described below through specific embodiments.

[0036] The present invention provides a fast face image beautification method that combines skin roughness and skin color similarity. First, the face image is converted from RGB color space to YCbCr color space, and the brightness component, blue chromaticity component and red chromaticity are respectively extracted Component map; secondly, combining the blue chromaticity component and red chromaticity component histogram, adaptively obtain the ellipse center and length radius of the skin color ellipse model, according to the skin color similarity, the skin color soft threshold map is obtained by the exponential function; then according to the skin color soft threshold Figure, the local variance of the brightness component is processed to obtain the local skin color variance map, the local skin color variance map is used as the smoothing parameter of the fast global smoothing filter, the b...

Abstract

The invention relates to a method of quickly beautifying a facial image in conjunction with skin roughness; the method comprises: converting the facial image from RGB space into YCbCr chrominance space, and extracting brightness component, blue chrominance component and red chrominance component graphs; solving an ellipse center and long and short radiuses of a skin color elliptical model in conjunction with blue chrominance component and red chrominance component histograms, and calculating a skin color soft threshold graph according to skin color similarity; processing brightness component to obtain a local skin color variance graph in conjunction with the skin color soft threshold graph, using the local skin color variance graph as a smoothing parameter and smoothing brightness component graph to perform Gaussian blurring on the soothing brightness component graph, and linearly mixing to obtain a smooth graph in conjunction with the brightness component graph; using the skin color soft threshold graph as a weight to fuse the brightness component graph and a smooth graph to obtain a fused graph, and subjecting the fused graph to curve whitening to obtain a finally beautified graph. The method uses skin color similarity and roughness to remove skin color defects while retaining the skin nature, and has significant overall beautifying effect.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a fast human face image beautification method combined with skin roughness. Background technique [0002] In recent years, with the maturity of digital camera or smart phone photography technology, the resolution of imaging is getting higher and higher, which can more clearly show the details of human face skin, such as freckles, wrinkles, acne, etc., which affect the human face. The beauty of the image. With the continuous improvement of aesthetic concepts, the requirements for display image quality and aesthetics are getting higher and higher. People hope to show beautiful face images. Therefore, the rapid beautification technology of face images is widely used in digital cameras, mobile terminals, advertising, It has a wide range of applications and practical value in multimedia such as conferences. [0003] At present, face beautification technology has become a research hot...
