Face cartoon image design method

Abstract

The invention provides a face cartoon image design method, and the method comprises the steps: 1, obtaining a face image; 2, collecting a plurality of feature points of the image, constructing a feature vector of a human face through the feature points, and constructing a face attribute topological graph which represents the topological structure of all organs of the human face and has certain tolerance to the deformation of the human face, wherein each top point in the topological graph represents one feature vector which is used for recording the feature information of the feature points nearby the top point; 3, building a cartoon image database through combining the feature vectors of the human face, the face attribute topological graph and a curvature line of the contour line of the human face; 4, comparing the feature points with the database, and extracting a cartoon image; 5, carrying out the rendering and special effect processing of the cartoon image, and generating a face ofa cartoon figure model; 6, detecting the key information of the face of the cartoon figure model, and outputting the key information to a mobile terminal. The method achieves the visualization of theface cartoon, solves problems of rigid and inflexible lines of faces, and meets the entertainment demands of users.

Description

technical field [0001] The invention belongs to the field of animation design, and in particular relates to a method for designing a human face cartoon animation image. Background technique [0002] Animation production is an emerging industry in our country, among which the design and application of cartoonized faces are very popular. At present, the face cartoon animation design usually extracts the facial features, retains the facial organ features, obtains the initial sample of the face sketch portrait, and then processes the initial sample to obtain a human face cartoon. However, the generated face cartoon has a large gap compared with photos or video collection, and the lines are rigid, rigid, and rigid, which cannot meet the entertainment and interactive needs of users. Therefore, it is an urgent problem to be solved urgently to develop a kind of face cartoon animation figure design method. Contents of the invention [0003] In view of this, the present invention ...
