On Adaptive Transmission for Energy Efficiency in Wireless Data Networks
Adaptive transmission broadcast energy-efficient transmission iterative algorithm multiple-access power control scheduling time-division wireless networks
2015/8/12
This paper investigates the problem of energy-efficient transmission of data packets in a wireless network by jointly adapting to backlog and channel condition. Specifically, we consider minimum-energ...
Block-Wise Adaptive Motion Accuracy Based B-Picture Coding With Low-Complexity Motion Compensation
Motion Accuracy B-Picture Coding Low-Complexity Motion Compensation
2010/12/16
This paper presents a novel B-picture coding based on block-wise adaptive motion accuracy (BAMA) with lowcomplexity motion compensation (MC). BAMA is able to adaptively
select the motion accuracy for...
Macroblock-Level Adaptive Scan Scheme for Discrete Cosine Transform Coefficients
Macroblock-Level Discrete Cosine Transform Coefficients
2010/12/17
Discrete Cosine Transform (DCT) has been widely used in image/video coding systems, where zigzag scan is usually employed for DCT coefficient organization. However, due to local
diversity of predicti...
An edge-based median filtering algorithm with consideration of motion vector reliability for adaptive video deinterlacing
filtering algorithm motion vector reliability
2010/12/16
Because of its ability to preserve signal edges while filtering out impulsive noises, median filtering is widely used in signal processing applications, e.g. deinterlacing. An edgebased
median filter...
