Deformation-Graph-Driven and Deformation Aware Spectral Pose Transfer

A deformation graph driven and deformation aware spectral pose transfer method is proposed in order to improve the ability of the spectral pose transfer method in preserving shape details and reducing user interac-tions.First,a deformation graph is introduced to drive the source model deforming under the guidance of low-frequency spectral coefficients of the reference model to obtain a deformed source model.Second,the de-formed source model is automatically segmented to parts according to the deformation.Third,repeating the spec-tral pose transfer on two source parts separately yields two deformed source parts.This process can be repeated again if necessary.Finally assembling all deformed parts in a reversed order results in the completely deformed source model.Comparison with the method of Yin et al.is conducted via a couple of examples.Experimental results show that the secondary pose migrations are reduced by 38%,the average distance error is reduced by 54%,and both surface area and volume variations are reduced by about 12.5%.It improves the quality of transfer results to a certain extent,reduces the number of middle-frequency pose transfer,and also reduces manual interaction.
