Wavelet-based volume morphing
Tingshu He, Sidney Wang, Arie E. Kaufman · 1994
This paper presents a technique for performing volume morphing between two volumetric datasets in the wavelet domain. The idea is to decompose the volumetric datasets into a set of frequency bands, apply smooth interpolation to each band, and reconstruct to form the morphed model. In addition, a technique for establishing a suitable correspondence among object voxels is presented. The combination of these two techniques results in a smooth transition between the two datasets and produces morphed volume with fewer high frequency distortions than those obtained from spatial domain volume morphing. 1. Introduction and motivation Recently, 3D metamorphosis, the process of simulating the deformation of one 3D model to another, has gained popularity in animation and shape design. Previously published techniques [5, 6] deal mainly with the metamorphosis between two polygonal-based models. The general method of these algorithms is to displace the vertices, edges, and faces of the first model ...
