In this correspondence, we address the task of recovering shape-from-focus (SFF) as a perceptual organization problem in 3-D. Using tensor voting, depth hypotheses from different focus operators are validated based on their likelihood to be part of a coherent 3-D surface, thereby exploiting scene geometry and focus information to generate reliable depth(More)
We are dealing with two different problem scenarios in two different layers. In MAC layer a problem known as Contention Window Cheating's existence has been discovered recently. In this paper, we propose a cross layer solution for the contention window cheating problem. Our solution is implemented based on congestion details provided by the Transport layer(More)
The effects of congestion can be seen in Figure 11.1. As shown in the figure, the throughput of a connection increases as the offered load increases until a point when the queues in the system start to fill up and the increase in throughput levels off. When the offered load becomes too large and the buffers are totally filled up, packets begin to get(More)
