A classical problem of imaging--the matting problem--is separation of a non-rectangular foreground image from a (usually) rectangular background image--for example, in a film fram...
Effective spectrum sensing is a critical prerequisite for multi-channel cognitive radio (CR) networks, where multiple spectrum bands are sensed to identify transmission opportuniti...
This paper addresses the problem of optimizing the packet transmission schedule in an ad hoc network with end-toend delay constraints. The emphasis is to determine the proper rela...
