Fast Fourier Transform using MPI libraries (Source Code)

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 ...

the attached utility is a work I ve submitted to the university It shows what a jpeg compression is all about. the function implements the DCT transform, using a matrix operator. note that matlab has a function for the DCT and iDCT transforms that might be more efficient.

Directional Multiscale Modeling of Images Using the Contourlet Transform

8点基二fft Fast Fourier Transform (FFT). Using 8 points, takes about 1.2 ms to execute one FFT. Sets up General Purpose Timer 1 to generate events at 10 kHz. Will produce 10 kHz output on T1PWM and T1PWM pins.
