碩士 === 國立暨南國際大學 === 資訊工程學系 === 98 === Modeling 3D caricaturing face is an interesting and practical research topic in the field of computer graphics. However, there is still lack of tool to transform a 2D human face image into a 3D comic face with the important features been preserved. Most of the methods proposed for caricaturing face synthesize 2D facial images. In the pre-processing steps, facial feature and facial contour are extracted by adopting image processing methods such as contour detection. The input image is then transformed into the caricature image with a specific NPR (Non-Photorealistic Rendering) style, such as watercolor, oil painting, or pencil sketch. In this paper, we propose a different approach which converts a 2D face image into a 3D caricaturing model. This 3D caricaturing model can be useful for making and customizing 3D cute figures. We use the DXUT (The DirectX Utility Library) framework to develop a user interface, and adopt the computer vision library - Open CV ( Open Source Computer Vision Library ) to automatically detect important positions of several facial features. And then, users are asked to click and drag the feature point to adjust a controlling facial mask. After the controlling facial mask has fit the input facial image, the corresponding mesh model is determined and deformed. The shape of eyes and mouth is also extracted to synthesize cartoon-like images which are used later for the purpose of texture mapping.
