Problems solved by technology

Since the above methods all belong to the global transformation of the eyes, and do not consider the local transformation problem, therefore, in the process of fitting the eye makeup, it is easy to produce distortion of proportion and shape, and the cosmetic effect is poor
Moreover, the existing method

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Step 101, obtaining a pre-stored standard face image, and performing eye image processing on the standard face image to obtain a first eye contour control point;

[0026] Step 102, acquiring a face image to be detected, and performing eye image processing on the face image to be detected to obtain a second eye contour control point;

[0027] In the embodiment of the present invention, step 101 and step 102 do not have a strict execution order, and may be executed sequentially or simultaneously. However, the eye image processing process for the standard face image and the test face image should be the same.

[0028] Specifically, the method for obtaining the first eye contour control point and the second eye contour control point is: perform eye key point p...

Abstract

The invention discloses an eye makeup mapping method based on mesh deformation. The method comprises a step of acquiring a standard face image and a face image to be detected and processing the imagesto obtain a first eye contour control point and a second eye contour control point, a step of performing area division on eyes of the standard face image and generating mesh vertexes in divided areas, a step of calculating a deformation function according to the first eye contour control point, the second eye contour control point and the mesh vertexes, a step of carrying out local deformation oneye makeup material texture sampling coordinates in the mesh vertexes by using the deformation function, a step of generating a triangular mesh surface according to the deformed mesh vertexes, a stepof creating an OpenGL vertex cache by using the deformed mesh vertexes, a step of creating an OpenGL index cache by using the triangular mesh surface, and a step of attaching a makeup material to theface image to be detected according to the vertex cache and the index cache. According to the technical scheme provided by the invention, an eye makeup material can accurately and naturally fit various eye shapes, a makeup effect is improved, and at the same time, the makeup time can be shortened.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an eye makeup mapping method based on grid deformation. Background technique [0002] In recent years, portrait beauty and makeup applications have become popular among young female users. Eyes are the "windows of the soul", and eye makeup is the most easily perceived by users. In the application of beauty and beauty makeup, apart from the authenticity and creativity of the eye makeup material itself, the most important technical indicator for the eye makeup effect is the accuracy of the eye makeup material fitting on the eye area, that is, How to apply local warp technology to an eye makeup material to accurately and naturally fit various eye shapes. [0003] The existing eye makeup mapping method mainly uses the method of eye deformation, that is, a transformation matrix is ​​calculated according to the eye contour control points of the standard face and the eye cont...
