ScrewBender: Smoothing Piecewise Helical Motions
An ordered series of control poses may be interpolated by a polyscrew (piecewise helical) rigid body motion composed of a series of screws, each interpolating a pair of consecutiv...

On geometric interpolation of parametric surfaces
By exploiting the freedom in the choice of parametrization of a parametric surface, we show that there exist quadratic parametric surfaces that approximate a given parametric surf...

Duality and Riemannian cubics
Riemannian cubics are curves used for interpolation in Riemannian manifolds. Applications in trajectory planning for rigid bodiy motion emphasise the group SO(3) of rotations of E...

Fast construction of accurate quaternion splines
In 1992, Barr et al. proposed a method for interpolating orientations with unit quaternion curves by minimizing covariant acceleration. This paper presents a simple improved metho...

Image Compression With Downsampling And Overlapped Transform At Low Bit Rates
This paper proposes an image coding method based on adaptive downsampling which not only uses the pixel redundancy but also considers visual redundancy. At the encoder side, codec...
