New controls for combining images in correspondence

Multiscale edge-aware melding of geometry and shape from two images.
When interpolating images, for instance in the context of morphing, there are myriad approaches for
defining correspondence maps that align structurally similar elements. However, the actual interpolation
usually involves simple functions for both geometric paths and color blending. In this paper we explore
new types of controls for combining two images related by a correspondence map. Our insight is to apply
recent edge-aware decomposition techniques, not just to the image content but to the map itself. Our
framework establishes an intuitive low-dimensional parameter space for merging the shape and color from the
two source images at both low and high frequencies. A gallery-based user interface enables interactive
traversal of this rich space, to either define a morph path or synthesize new hybrid images. Extrapolation
of the shape parameters achieves compelling effects. Finally we demonstrate an extension of the framework
