Abstract: Spectral pose transfer based on deformation graph is proposed to reduce the influence of the geometry agent Cage. At the beginning, the deformation graph is obtained to optimize the quadric error metric algorithm so as to simplify the source mesh, and then the deformation graph vertices are used to represent the source mesh vertices through the geodesic distance. The source mesh vertices are forced to be identical as much as possible with the results of pose transfer based on the coupled quasi-harmonic basis, and the same time, the Laplacian coordinates of the deformation graph are kept and then the result of the low frequency pose transfer can be obtained on the basis of optimizing the related result by applying the embedded deformation algorithm. After that, the local meshes of insufficient secondary pose study are found by observation and then are divided into the sub-meshes. The secondary pose is transferred by using the low frequency pose transfer method on these sub-meshes. Experimental results show that it can reduce the influence of geometry agent to some extent, and can also effectively improve the pose transfer.
