Fast Fourier Transform using MPI libraries (Source Code)

A basic Fourier transform identity coupled with an iterative convergence algorithm provides a powerful method to align band-limited signals.

Contourlet is a new approach in image transform. There have something better than Fourier and Wavalet transform.

Abstract—The contourlet transform is a new two-dimensional extension of the wavelet transform using multiscale and direc- tional &#64257 lter banks. The contourlet expansion is composed of basis images oriented at various directions in multiple scales, with &#64258 exible aspect ratios. Given this ...

These documents are all classic documents relating to the domain of virus writing.Give a good insight about the virus which are rare and are considered best for case studies..many variants are still being produced and all these are original.Its very hard to find them now adays..these are extremely h ...
