A new scintillator-based fast ion loss detector has been installed on DIII-D with the time
response (> 100 kHz) needed to study energetic ion losses induced by Alfvén eigenmodes …

Digital video is becoming ubiquitous, thanks to tremendous technological progresses over
the last decades, with widespread applications in information technology …

In video sequences, motion is a key source of information. Motion arises due to moving
objects in the 3D scene, as well as camera motion. Apparent motion, also known as optical …

To reduce temporal redundancies appearing in video sequences block based motion
estimation techniques have been successfully applied. However, due to the block-based …

This paper presents a technique to segment and track a region of interest in a video
sequence. The presented technique starts with a spatio-temporal contour extraction. This …

In low bit-rate video transmission, the payload of a single packet can often contain a whole
coded frame due to the high compression ratio in both spatial and temporal domains. Thus …

This paper presents a technique to segment and track a region of interest in a video
sequence. The presented technique starts with a spatio-temporal contour extraction. This …

This paper describes a contour-based representation of images. More particularly, we
discuss a method of representing image data which is a resolution-independent scheme …
