A novel method is introduced for the generation of landmarks for three-dimensional (3-D)
shapes and the construction of the corresponding 3-D statistical shape models. Automatic …

The authors have devised, implemented, and tested a fast, spatially accurate technique for
calculating the high-dimensional deformation field relating the brain anatomies of an …

A representation of objects by their parts is the dominant strategy for representing complex
3D objects in many disciplines. In computer vision and robotics, superquadrics are among …

This paper presents a method for segmentation and tracking of cardiac structures in
ultrasound image sequences. The developed algorithm is based on the active contour …

We present a method for nonrigid motion analysis in time sequences of volume images (4D
data). In this method, nonrigid motion of the deforming object contour is dynamically …

Automatic prostate segmentation in ultrasound images is a challenging task due to speckle
noise, missing boundary segments, and complex prostate anatomy. One popular approach …
