Abstract

The invention discloses a lip makeup simulation method and system based on a two-color reflection model. First, a method for establishing a lip makeup data set is proposed. On this basis, the two-color reflection model is used as a guiding ideology to input target images and cosmetic color samples Separation of the specular highlight and the diffuse reflection part, and then simulate the makeup effect from the diffuse reflection component and the specular reflection component, and finally synthesize the simulation effect of the lip makeup. The present invention establishes a new makeup data set. While considering the illumination and personal characteristics, it uses the deep learning network to conveniently simulate lip makeup. In addition, it also considers the difference between diffuse reflection and specular reflection of cosmetics. The effects simulate color changes and highlight changes after applying cosmetics.

Description

technical field [0001] The invention belongs to the technical field of computer graphics and artificial intelligence, and relates to a lip makeup simulation method and system, in particular to a lip makeup simulation method and system based on a two-color reflection model. Background technique [0002] Throughout the ages, human beings have been tirelessly pursuing beauty, and makeup is one of the powerful means. Nowadays makeup has become a daily routine for many people, along with the cosmetics industry. With the vigorous development of cosmetics, there are endless types and styles of cosmetics. It is the appeal of most buyers to choose the cosmetics that suit them to achieve the ideal makeup modification effect. [0003] Offline makeup testing is the most direct way to choose cosmetics. However, this method is also the most time-consuming and labor-intensive. At the same time, the popularity of online shopping has reduced the frequency of shopping for many people. Theref...
