Solving for Motion and Activation Simultaneously in an fMRI Experiment with Multiple Stimulus Conditions
It has recently been shown that greater accuracy in fMRI processing can be achieved if registration and activation detection are solved simultaneously rather than in sequence. How...

Speckle Reduction on Ultrasound Image by Variational Methods and Adaptive Lagrangian Multipliers
Ultrasound images are corrupted by a multiplicative noise, the speckle, which makes high level analysis difficult. Within each resolution cell a number of elementary scatterers re...

Cortical Surface Flattening Using Least Square Conformal Mapping with Minimal Metric Distortion
Although flattening a cortical surface necessarily introduces metric distortion due to the non-constant Gaussian curvature of the surface, the Riemann Mapping Theorem states that ...
