Matrix Encoding for Data Hiding Using Multilayer Video Coding and Transcoding Solutions
This paper proposes a multitier data hiding solution in MPEG video using matrix encoding. In the first tier of the proposed solution, raw video is encoded into two layers using multilayer Signal to Noise Ratio (SNR) encoding. ...
Data Hiding in MPEG Video Files Using Multivariate Regression and Flexible Macroblock Ordering
This paper proposes two data hiding approaches using compressed MPEG video. The first approach hides message bits by modulating the quantization scale of a constant bitrate video. A payload of one message bit per macroblock ...
Defining an Architectural Design Strategy for Energy Performance-A Systematic Approach for Students
(American Society of Civil Engineers, 2012)
Managing the energy performance of a building should start from the pre-conceptual design phase. Architects at this phase need to analyze the nature of the site environment, the nature of the building, and the comfort ...
Convergence rate of the binomial tree scheme for continuously paying options
(Université du Québec à Montréal, 2012)
Continuously Paying Options (CPOs) form a very natural class of derivatives for hedging risks coming from adverse movements of a continuously traded asset. We study the rate of convergence of CPOs evaluated under the ...
