基于照片的可编辑光照效果卡通人脸生成算法
摘要: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。
Abstract: An algorithm generating human face cartoon portrait including light editing is presented#br# based on photo. The algorithm first extracts the contour of the input image to generate the line#br# drawing. Secondly, the intrinsic image decomposition method is used to produce the shading and#br# reflectance image. Then the illumination image is edited by using of methods such as quantization,#br# nonlinear enhancement, and the cartoon image is produced combining the abstracted reflectance#br# image with line drawing. Finally, edited illumination image is added to the cartoon image to generate#br# the facial cartoon portrait with illumination effects. The experimental results show that the generated#br# facial cartoon portrait looks lifelike by our algorithm which has the function of editing illumination.
