The paper presents a new method to detect forgery by copy-move, splicing or both in the same image. Multiscale, which limits the computational complexity, is used to check if there is any counterfeit in the image. By applying one-level Discrete Wavelet Transform, the sharped edges, which are traces of cut-paste manipulation, are high frequencies and detected from LH, HL and HH sub-bands. A thre...

The stochastic resonance (SR) is a phenomenon in which adding a moderate amount of noise can improve the signal-to-noise ratio and performance of non-linear systems. SR occurs in all sensory modalities including the visual system in which noise can enhance contrast detection sensitivity and the perception of ambiguous figures embedded in static scenes. Here, we explored how adding background wh...

The discrete Fourier transform-rational dither modulation (DFT-RDM) has been proposed as a way to provide robustness to linear-time-invariant (LTI) filtering for quantizationbased watermarking systems. This scheme has been proven to provide high rates for white Gaussian hosts but those rates considerably decrease for non-white hosts. In this paper the theoretical analysis of DFT-RDM is generali...

Literature on technology and innovation management has identified the research and development (R&D) and marketing (RDM) interface as a critical organizational complexity that when managed well can affect company success in innovation. Cross-functional teams and collaboration mechanisms, such as boundary spanners, have been identified as solutions to the problems in communication between the tw...

We present a text mining approach that discovers patterns at varying degrees of abstraction in a hierarchical fashion. The approach allows for certain degree of approximation in matching patterns, which is necessary to capture non-trivial features in realistic datasets. Due to its nature, we call this approach Recursive Data Mining (RDM). We demonstrate a novel application of RDM to role identi...
