摘要
将薄平面样条函数用于人头模型的调整 ,使模型调整变得更加平滑、自然 ,并在纹理映射时 ,提出了基于模型分块的视角相关纹理映射的方法 ,该方法将模型分块并用每块对应的最清晰、非冗余的纹理对模型块做映射 ,使块与块之间形成的规则过渡带非常易于纹理融合 ,整个模型逐块地一次绘制完成 ,然后在模型中嵌入了抽象的人脸肌肉 ,合成出非常逼真的人脸表情动画 实验表明文中算法快速、简捷 ,合成的人脸图像细节清晰。
In this paper, the smoothness of thin-plate spline is applied to the model adaptation, which makes the adapted model smoother and more realistic In texture mapping, a new method of model blocking based view-dependent texture mapping is proposed In this method, the model is divided into parts first and each part is mapped with the clearest and non- redundant texture It makes the transition band between blocks very much regular and the blending of texture blending easily The model is rendered one time block by block Then, abstract muscles are embedded into the model and realistic face expressions are synthesized Experiments indicate that the algorithm is fast and compact, and the face synthesized is very realistic, with the face details are clearly produced very much
