A novel identification approach for identifying photographic images (PIM) and photorealistic computer graphics (PRCG) is proposed by using multifractal spectrum features of photo response non-uniformity noise (PRNU). 8 dimensions of mul-tifractal spectrum features of PRNU are extracted to represent the subtle differences between them, and the identification is carried out by using a support vector...
The purpose of this paper is to analyze the differences of distributed flight reference (DFR) and non-distributed flight reference (NDFR) from an ergonomics perspective, for the design of more practical and efficient helmet-mounted display(HMD). Eye tracking technology was adopted in this study to compare these two different information formats. Static pictures of two flight references were used as...
A simple yet accurate analysis of the bit error rate performance for differential chaos shift keying communication system is proposed for an additive white Gaussian noise channel by using the non-central F distribution of the decision variable and assuming variable bit energy in the calculation. The new method has much higher accuracy or much lower computational complexity than the existing methods...
Empirical evidence shows the presence of a jump component in addition to the diffusion component in the evolution of asset prices. In this article, jump-diffusion model described the underlying stock price dynamics. An approach of extrapolation acceleration was developed to yield a simple and efficient computation procedure for practical pricing of American call option on a stock with continuous dividends...
