Towards a contour morphing preserving differentiability

Image Metamorphosis based on Elastic Body Spline and Snake Model

Image metamorphosis ( For short, image morphing ) is an active eld of research and recent e orts aim at improving both user interface and warping results. Generally, the morphing technique involves three problems. The rst is to establish correspondence between given two images, which is most di cult part of morphing process. The correspondence is usually established by hand. The second problem ...

Piecewise-Bézier C1 Interpolation on Riemannian Manifolds with Application to 2D Shape Morphing

We present a new framework to fit a path to a given finite set of data points on a Riemannian manifold. The path takes the form of a continuously-differentiable concatenation of Riemannian Bézier segments. The selection of the control points that define the Bézier segments is partly guided by the differentiability requirement and by a minimal mean squared acceleration objective. We illustrate o...

High level emotional speech morphing using STRAIGHT

This paper presents high-level strategies for controlling emotional speech morphing algorithms. Emotion morphing is realized by representing the acoustic features in their timefrequency plan that is warped and modified to generate natural morphed emotional speech. These acoustic features are desirable to be decomposed into multidimensional space and to be orthogonal. After matching these acoust...

Morphing Polyhedra Preserving Face Normals: A Counterexample

Towards Open-Set Identity Preserving Face Synthesis

We propose a framework based on Generative Adversarial Networks to disentangle the identity and attributes of faces, such that we can conveniently recombine different identities and attributes for identity preserving face synthesis in open domains. Previous identity preserving face synthesis processes are largely confined to synthesizing faces with known identities that are already in the train...
