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 …

Branch prediction has enabled microprocessors to increase instruction level parallelism
(ILP) by allowing programs to speculatively execute beyond control boundaries. Although …

This chapter addresses the development of a new approach to motion estimation which rely
on a semantic representation of the scene in terms of objects. More specifically, motion …

This paper highlights some problems related to the identification of parametric motion
models in image sequences by the so-called differential methods. This often entails the bad …

Motion estimation is a key issue in video coding. In very low bitrate applications, the amount
of the side information for the motion field represents an important portion of the total bitrate …

For the past decade, the region-based approach, that combines object segmentation and
optical flow estimation, has emerged as the only one likely to provide automatically, at a …

This report describes an image sequence coding scheme with motion compensation. In
order to use the inter-images redundancies in an image sequence, the motion between the …

This paper introduces an improved variable size block based motion estimation algorithm
relying on a hierarchy of motion representations. The most efficient of the latter is chosen …

The block-recursive algorithm for motion estimation is an option to classical methods like
block-matching usually used in conventional coding schemes based on motion …

De nombreuses applications en vision par ordinateur nécessitent la détection et le suivi des
objets en mouvement dans une séquence d'images. Le but de ce travail est de détecter et …
