Abstract: Devices, softwares and methods for wireless devices to form a network on the fly by performing admission control while in the second layer, without going to the third layer. A peripheral station encodes a priority of data in a tag that is transmitted in a reservation request frame. A cooperating complementary access point receives the reservation request frame and reads the tag. The request is finally resolved (granted or denied) at the second level, using the priority information of the tag.

Abstract: A method and apparatus for tracking of objects in video images. The tracking process includes the steps of: receiving an initial image with the object to be tracked; performing a color histogram on the initial image in the region where the object is located; receiving the next frame of the video sequence and specifying candidate regions in that image; using color histogram analysis on the candidate regions to find a match performing motion analysis to correct the analysis and to provide a prediction for the next frame; and, identifying and providing the tracked object's image for output. Apparatus that can use this method can be either video capture or video display. In video capture, a user interface allows the user to designate the object to be tracked during capture. The tracking module than controls the capture system to track that object. In video display systems, a user interface allows the user to identify the object in the display that should be tracked.
