In recent years of digital world, a lot of interest has been emerged in the optical fiber. In this paper, we are modelling the spectral attenuation and central dip in refractive index profile parameters in an optical fiber. The feasibility and practicability of modeling and analysis of the spectral loss of an optical fiber is performed using an algorithm to a single multi-parameter equation. In that,...
Detection of unexploded ordinance (UXO) and Landmines is a priority task even after the wars have been over. Ground Penetrating Radar (GPR) proved to be an effective technology for applications like the buried object detection. It is suitable not only for the metallic objects, but it can also detect wood and plastic object. Despite of its many advantages, detection becomes difficult due to major limitations...
In a digital watermarking scheme, it is not convenient to carry the original image all the time in order to detect the owner's signature from the watermarked image. Moreover, for those applications that require different watermarks for different copies, it is preferred to utilize some kind of watermark-independent algorithm for extraction process i.e. dewatermarking. Watermark embedding is performed...
