Embodiment Construction

[0049] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited thereto.

[0050] The principle of the embodiment of the present invention is to take pictures with a camera to obtain clear photos of faces, obtain facial contours and facial features through image recognition, and parameterize facial features. Then, through the rendering engine on the server side, according to the facial contour features, search for cartoon avatars that match the appropriate animation image in the animation avatar library, and then perform corresponding proportional mapping according to the original facial features, and automatically generate an animation corresponding to the animation image of the given face Cartoon face avatars, in order to achieve the highest similarity.

[0051] The embodiment of the present invention relates to a mobile phone application c...

Abstract

The invention provides a method for cartooning a human face and a system thereof. The method of the invention comprises the steps of: acquiring a human face photo through a camera; gridding the human face photo and extracting characteristic points; modeling the human face photo and the characteristic points after gridding, and retrieving a matched cartoon head portrait from a cartoon database; deforming the cartoon head portrait according to the characteristic points; performing texture mapping and rendering on the cartoon head portrait after deformation, and obtaining the cartoon human face head portrait; and outputting the cartoon human face head portrait. Compared with the prior art, the method of the invention realizes cartooning of the human face, and settles the following problems in human face cartooning: stiff effect, rigid line and no charm. Furthermore, through data exchange between a mobile phone end and a service end, high mobility, high practicality and high usability of the terminal are realized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for visualizing human face cartoon animation. Background technique [0002] With the development of mobile communication technology, various applications appear in the terminal field. Among them, the application of face cartoonization is very popular. At present, the scheme of face cartoonization technology mainly focuses on face sketch avatar. Usually, after the face feature extraction based on pattern recognition, a grayscale image is calculated, and then the method based on the full variation model in the logarithmic domain is used to smooth out the skin texture and retain the facial organ features to obtain a face sketch The first sample of the portrait, and then perform image enhancement processing on the first sample of the face sketch portrait to obtain the final face sketch portrait. [0003] In view of the wide application of pattern r...
