基于照片的可编辑光照效果卡通人脸生成算法

An Algorithm Generating Human Face Cartoon Portrait Including Light Editing Based on Photo

提出一种基于照片的可编辑光照效果卡通人脸图像生成算法。算法首先提取输入人脸照片的边缘轮廓,生成线条画;其次对输入照片进行本征分解,分离出光照图像和材质图像;然后对光照图像进行光照编辑,如量化、非线性增强等;对材质图像进行抽象化处理,并融合线条画得到卡通图像;最后将编辑过的光照图像添加到卡通图像上生成含有光照效果的人脸卡通图像。实验结果表明:该算法生成的人脸卡通图像效果逼真,并且可对光照进行编辑。

An algorithm generating human face cartoon portrait including light editing is presented based on photo. The algorithm first extracts the contour of the input image to generate the line drawing. Secondly, the intrinsic image decomposition method is used to produce the shading and reflectance image. Then the illumination image is edited by using of methods such as quantization, nonlinear enhancement, and the cartoon image is produced combining the abstracted reflectance image with line drawing. Finally, edited illumination image is added to the cartoon image to generate the facial cartoon portrait with illumination effects. The experimental results show that the generated facial cartoon portrait looks lifelike by our algorithm which has the function of editing illumination.
