In this paper, we use gradient adjacent prediction to present a new data hiding method based on histogram. Our method can increase the amount of hidden data, and keep higher PSNR of stego-image. According to experiment results, our method increases the amount of hidden data by 12.5% on the average as compared with Jang et al.’s method.

In this paper, we propose an algorithm of angular mode selection for high-performance HEVC intra prediction. HEVC intra prediction is used to remove the spatial redundancy. Intra prediction has a total of 35 modes and block size of 64x64 to 4x4. Intra prediction has a high amount of calculation and operational time due to performing all 35 modes for each block size for the best cost. The angula...

A new event detection scheme for power quality analysis based on the statistical analysis of adaptive decomposition signals is proposed. Proposed scheme is implemented using MATLAB Simulink DSP Blockset. The combination of an adaptive prediction filter based subband decomposition structure with a rule based histogram analysis block produced successful detection and classification results on ou...

The meaning and characteristics of the virtual experiment and the significance of applying virtual prototype into agricultural equipment were analyzed in this paper. Then a kind of virtual experiments system platform on agricultural equipments was founded by using MultiGen Creator, Vega Prime software and VC++ programming language. According to the functions of the virtual experiment system, th...

In this paper, we propos e a new algorithm in reversible data hiding, with the applications of copyright and privacy protection for natural image s. Security issues for digital images have long been an important topic in research and practical applications, and reversible data hiding has attracted more and more attention. Unlike conventional schemes, we take the prediction of luminance values a...

We examine the charmless hadronic B decay modes in the context of R-parity violating (Rp / ) supersymmetry. We try to explain the large branching ratio (compared to the Standard Model (SM) prediction) of the decay B → ηK. There exist data for other observed η(′) modes and among these modes, the decay B0 → ηK∗0 is also found to be large compared to the SM prediction. We investigate all these mod...

Abstract With the advancement of communication technology, a large number data are constantly transmitted through internet for various purposes, which prone to be illegally accessed by third parties. Therefore, securing such is crucial protect information from falling into wrong hands. Among protection schemes, Secret Image Sharing one most popular methods. It protects critical messages or embe...
