Gabor-Like Image Filtering for Transient Feature Detection and Global Energy Estimation Applied to Mout interruption. The current paper proposes a new method for the automatic segmentation of “emotional segments” and the dynamic recognition of the corresponding facial expressions in video sequences. First, a new spatial filtering method based on Log-Normal filters is introduced for the analysis of

Improving Ventricle Detection in 3–D Cardiac Multislice Computerized Tomography Imagesas been tested using 4–D (3–D+ time) cardiac Multi–Slice Computerized Tomography (MSCT) images. The generalized Hough transform and a seed based clustering procedure are integrated into the segmentation method. The method also considers an image enhancement step that consists in applying the mathema

Interactive Rigid Body Dynamics Using a Projected Gauss–Seidel Subspace Minimization Methodorces. This paper addresses the contact force problem, as used in interactive simulation. Contact forces are applied to prevent rigid bodies from penetrating and to control slipping between bodies. Accurate contact force determination is a computationally hard problem. Thus, in practice one trades a
