Colour Guided Colour Image Steganography
Information security has become a cause of concern because of the electronic eavesdropping. Capacity, robustness and invisibility are important parameters in information hiding and are quite difficult to achieve in a single algorithm. This paper proposes a novel steganography technique for digital color image which achieves the purported targets. The professed methodology employs a complete ran...
متن کاملNew recording materials for holography
Some of the alternative silver halide materials that can be considered to replace the previous Agfa Holotest materials are discussed. The characteristics of Slavich and HRT materials are examined, including the special aspects of recording and processing ultrahigh-resolution silver halide materials. These materials can offer a significant improvement in product quality. The sensitivity is lower...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
متن کاملInner Products and Orthogonality in Colour Recording Filter Design
noise, sensitivity, digital cameras, scanners, color, colour We formalize ideas of orthogonality and inner products implicit in the development of a number of figures of merit (FOM, [1]) of colour recording filters. We show that, in negligible measurement noise, the data dependence of each FOM based on linear colour correction is equivalent to a choice of inner product (and hence of orthogonali...
متن کاملComprehensive Colour Image Normalization
The same scene viewed under two diierent illuminants induces two diierent colour images. If the two illuminants are the same colour but are placed at diierent positions then corresponding rgb pixels are related by simple scale factors. In contrast if the lighting geometry is held xed but the colour of the light changes then it is the individual colour channels (e.g. all the red pixel values or ...
