This paper presents some power results of Joint Photographic Experts Group (JPEG) in Field-Programmable Gate Array (FPGA) and provides some analysis and results in reduced dynamics-power methods of it. The dynamic power consumed by a digital CMOS circuit is directly proportional to both switching activity and payload capacitance. We use Xilinx XPower Analyzer to analyze the impact of different switching...
Some work is done to improve embedding capacity and locate tampered regions base on the prior research of fragile document watermark in this paper. And an effective fragile document watermarking algorithm is proposed. The wet paper code which adjusts the number of embedding watermark bits dynamically and takes full advantage of turnover pixels is used for embed watermark to improve embedding capacity...
