Problems solved by technology

[0003] However, the styles of face cartoons drawn by artists are not exactly the same, and the drawing methods of different styles of cartoons are different. As the basis for automatic synthesis of face cartoons, how to build a unified parameterization that can satisfy different styles of cartoon samples The face cartoon sample space will be directly related to the generation effect and scope of application of the face cartoon drawing algorithm

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] The present invention comprises the following steps:

[0033] 1) Establish a parametric model of face cartoon samples

[0034] see figure 1 , the parametric model of the face cartoon sample is to divide the drawn face cartoon sample into a reference shape layer and a drawing style layer, which is recorded as Sample={R, P};

[0035] The reference shape layer divides the face object into the overall structure and the shape of the facial features, which is recorded as R=(M, S), M represents the overall structure of the face, and records the position information of the facial features and accessories; S represents the component set that composes the face object , defined by the facial features including left eyebrow, right eyebrow, left eye, right eye, nose, mouth and face geometry;

[0036] The drawing pattern layer is to divide the cartoon picture cor...

Abstract

The invention discloses a unified parametrization method of human face cartoon samples of diverse styles, comprising: representing picture composition and drafting of the human face cartoon samples layer by layer, Painting Style Parameters-PSP to define the picture composition of the cartoon samples, and Painting Entity Parameters-PEP to define the drafting of cartoons. With the unified parametrization data architecture, the drafting algorithm can completely learn picture composition and drafting of the human face cartoon samples according to geometrical characteristics of an authentic human face, and an individualized human face cartoon of a specific human face object can be automatically generated by sequential optimization calculation of PSP and deformation shift of PEP. And a computercan automatically learn drafting method of cartoons of diverse artistic styles, having good expandability and data independence.

Description

technical field [0001] The invention belongs to the field of computer vision and graphics and image processing, and in particular relates to a unified parameterization method of various styles of human face cartoon samples. Background technique [0002] The face cartoon samples drawn by human artists are parameterized to form a face cartoon sample space. By inputting human faces and learning the drawing method of cartoon samples, face cartoons of a specified style can be automatically synthesized. [0003] However, the styles of face cartoons drawn by artists are not exactly the same, and the drawing methods of different styles of cartoons are different. As the basis for automatic synthesis of face cartoons, how to build a unified parameterization that can satisfy different styles of cartoon samples The face cartoon sample space will be directly related to the generation effect and scope of application of the face cartoon drawing algorithm.
