Problems solved by technology

[0003] At present, some software can provide the function of adding lip gloss, but the degree of automation is not enough. Human assistance is required when adding lip gloss, such as the need to manually adjust the range of the lip area, or the added lip gloss cannot be adaptively changed according to the light and color changes of the original image. , the color transition of the added lip gloss is not natural enough; or the added lip gloss completely covers the lips of the original image, without retaining the texture of the lips of the original image, making the added lip gloss look unrealistic

Abstract

The invention provides a self-adaptive virtual lip gloss generation method and system. The method comprises the following steps of: obtaining lip key points in the face image; determining a lip area according to the lip key points; counting the average color of each pixel point in the lip area; generating a color mapping curve according to the counted average color and the reference lip gloss color; obtaining the brightness of each pixel point in the lip area and the average brightness of the lip area; wherein the lip gloss intensity function is used for representing the relationship between the brightness of each pixel point in the lip area and the added lip gloss intensity, and a step of adding lip gloss to the pixel points in the lip area according to the color mapping curve and the lipgloss intensity function. According to the method, the added lip gloss can be natural in color transition and clear in texture, the lip gloss can be added completely automatically and efficiently, and the effect of improving the aesthetic feeling of portraits is achieved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for generating adaptive virtual lip gloss.
