Title: NON-RIGID ALIGNMENT FOR VOLUMETRIC PERFORMANCE CAPTURE
Abstract:
An electronic device [100] estimates a pose of one or more subjects in an environment based on estimating a correspondence between a data volume [120] containing a data mesh [117] based on a current frame [105] captured by a depth camera [102] and a reference volume [125] containing a plurality of fused prior data frames based on spectral embedding and performing bidirectional non-rigid matching between the reference volume and the current data frame to refine the correspondence so as to support location-based functionality. The electronic device predicts correspondences between the data volume and the reference volume based on spectral embedding. The correspondences provide constraints that accelerate the convergence between the data volume and the reference volume.
