Abstract
Image-based synthesis for non-rigid bodies whose appearances do not form a linear manifold is carried out by representing mappings from control parameters to appearances as subsets of piecewise smooth functions. Each subset contains example images which are well approximated by particular examples which lie on the convex hull of the subset's parameter values. Once the subsets of examples are defined, interpolation is performed by using only the examples in a single subset. To provide for efficient operation, image transforms based upon radial cumulative similarities are used to automatically estimate the correspondence between example images.
