例如一组姿势被分解成硬骨转换和一个稀疏的,凸的骨顶点权重映射W(左侧)的块坐标下降算法(右手边)。在这个过程中,例如构成(作为蓝色点标示)可以重建更精确地,通过交替更新W和B,而另一个保持固定。 A set of example poses are decomposed into rigid bone transformations B and a sparse, convex bone-vertex weight map W (left hand side) by our block coordinate descent algorithm (right hand side). During the process, the example poses (indicated as blue dots) can be recons***cted more accurately by alternatively updating W and B while the other is kept fixed.
