In the process of matching a morphable model to image , the euclidean distance between the reconstructed 3d component image and the input component image is defined as the goal function . comparing with the whole face 3d morphable model , the dimension of each component is low and the scale of the goal function of each component is relatively small , so the optimized result is improved and the 3d component is more precise 在模型匹配过程中,定义相同视点下获得的三维部件图像与给定部件图像的误差作为目标函数,由于每个部件维数比较低,与整个面部的三维形变模型相比,目标函数的规模相对较小,优化效果得到改善,提取的三维部件特征更准确。
