A fast and memory-efficient algorithm for smooth interpolation of polyrigid transformations: application to human joint tracking

28 Apr 2020K. MakkiB. BorotikarM. GaretierS. BrochardD. Ben SalemF. Rousseau

The log Euclidean polyrigid registration framework provides a way to smoothly estimate and interpolate poly-rigid/affine transformations for which the invertibility is guaranteed. This powerful and flexible mathematical framework is currently being used to track the human joint dynamics by first imposing bone rigidity constraints in order to synthetize the spatio-temporal joint deformations later...
