Topology-Independent Region Tracking with Level Sets
This paper presents a new approach to the tracking of regions in an image sequence. Unlike most other methods, the proposed approach can handle topology changes, i.e., regions may...

A PDE characterization of the intrinsic mode functions
For the first time, a proof of the sifting process (SP) and so the empirical mode decomposition (EMD), is given. For doing this, lower and upper envelopes are modeled in a more c...

A Non-local Approach to Shape from Ambient Shading
We study the mathematical and numerical aspects of the estimation of the 3-D shape of a Lambertian scene seen under diffuse illumination. This problem is known as “shape from amb...

Inverse Biomedical Imaging Using Separately Adapted Meshes for Parameters and Forward Model Variables
Many important existing and upcoming biomedical imaging modalities lead to nonlinear relationships between state variables from which measurements result and the tissue properties...

A robust PDE solver for the 3D Stokes/Navier-Stokes systems on the grid environment
Since grid computing provides users with more distributed computing and storage resources, it gives us an opportunity to design new efficient and robust solvers for the numerical...
