Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] Such as figure 1 and figure 2 As shown, the present invention takes the input facial image I and the reference facial image ε as input, and outputs the result image It preserves the structure of the input facial image I while applying the makeup style of the reference facial image ε. The symbols used are listed in the table below.

[0065] Color balance process:

[0066] Such as figure 1 and figure 2 As shown, the present invention uses the OpenCV color balance algorithm to complete facial whitening. The OpenCV formula is as follows:

[0067] Among them, 0≤i, red, green, blue≤255. highlights_sub is defined as reducing highlights, midtones_add is defined as increasing midtones, and shadows_sub is defined as reducing shadows. i is defined as a 256-pixel index, red is defined as the pixel valu...

Abstract

The invention relates to a complex makeup migration method based on facial analysis and illumination migration. Facial analysis is combined with an illumination migration algorithm and a makeup migration algorithm. The method comprises the following steps: firstly, carrying out whitening and buffing preprocessing on an input face image by using a color balance and bilateral filtering algorithm; secondly, migrating makeup of the reference face image to the input face image by utilizing a face analysis and facial makeup migration algorithm, and finally migrating illumination of the reference face image to the input face image by utilizing an illumination migration algorithm to complete migration of complex facial makeup. The method is very easy to realize through software, and can be widelyapplied and popularized to computer vision, visual design, digital entertainment, film production and the like.

Description

technical field [0001] The invention belongs to the fields of visual computing and computer vision, in particular to a makeup transfer method, in particular to a makeup transfer method based on facial analysis and light transfer. Background technique [0002] Facial image makeup transfer is a new application requirement of computer vision technology in image. How to see the virtual makeup effect on the image meets the needs of the young female population. Authentic facial makeup is a technique of changing the appearance with special cosmetics such as foundation, loose powder, lotion, etc. In most cases, especially for women, makeup is a must to enhance the appearance. Lotions are often used to change the texture of facial skin, foundations are mainly used to hide imperfections and cover the original skin texture, and loose powders are used to introduce new, often pleasing textures to the skin. Finally, others such as eyeliner and shadow are usually applied on top of loose ...
