Multi-scale geometric detail enhancement for time-varying surfaces

This paper presents a new multi-scale geometric detail enhancement approach for time-varying surfaces. We first develop an adaptive spatio-temporal bilateral filter, which produces temporally-coherent and feature-preserving multiscale representation for the time-varying surfaces. We then extract the geometric details from the time-varying surfaces, and enhance geometric details by exaggerating detail information at each scale across the time-varying surfaces. Our approach can process mesh sequences with consistent connections or point sequences with unconstructed point set. In addition, as applications, based on the developed multi-scale surface representation and detail enhancement operators, we present geometric detail transfer, space-time morphing, and local regions detail enhancement for the time-varying surface.
