The Function Space of an Activity
2006 IEEE Computer Society Conference on Computer Vision and Pattern Recognition - Volume 1 (CVPR'06), 2006An activity consists of an actor performing a series of actions in a pre-defined temporal order. An action is an individual atomic unit of an activity. Different instances of the same activity may consist of varying relative speeds at which the various actions are executed, in addition to other intra- and inter- person variabilities.

Journal of Visual Communication and Image Representation, 2009
Deformable models have been widely used in image segmentation since the introduction of the snakes. Later the introduction of level set frameworks to solve the energy minimization problem associated with the deformable model overcame some limitations of the parametric active contours with respect to topological changes by embedding surface ...

Unbundling active functionality
ACM SIGMOD Record, 1998New application areas or new technical innovations expect from database management systems more and more new functionality. However, adding functions to the DBMS as an integral part of them, tends to create monoliths that are difficult to design, implement, validate, maintain and adapt.

Physiology of Functional Activation
2003Nearly all studies of task-specific activation using functional neuroimaging rely on the existence of a close coupling between regional changes in brain metabolism and regional cerebral blood flow (CBF), herein referred to as activation-flow coupling (AFC).

Activity and Function of Deadenylases
2012Shortening of the poly(A) tail is the first and often rate-limiting step in mRNA degradation. Three poly(A)-specific 3' exonucleases have been described that can carry out this reaction: PAN, composed of two subunits; PARN, a homodimer; and the CCR4-NOT complex, a heterooligomer that contains two catalytic subunits and may have additional functions in ...
