—Mobile devices performing video coding and streaming over wireless communication networks are limited in energy supply. In this paper, a power-efficient fast cloud-based Compressive Sensing (CS) video communication system framework is proposed, which shifts the heavy computational burden from mobile devices to cloud thus the operational lifetime of the(More)
—Compressive sensing (CS) is a new method of sampling and compression which has great advantage over previous signal compression techniques. However, its compression ratio is relatively low compared with most of the current coding standards, which means a good quantization method is very important for CS. In this paper, a new method of non-uniform(More)
