gpu_fft | Jeppe Revall Frisvad
| | Abstract | FFT class which computes two 2D fast Fourier transforms in parallel
on the GPU.
Assumes that GLEW is available and has been initialized.
Includes the load_shaders package.
Implementation is based on T. Sumanaweera and D. Liu. Medical Image
Reconstruction with the FFT. In GPU Gems 2: Programming Techniques
for High-Performance Graphics and General-Purpose Computation,
Chapter 48, pp. 765-784, Addison-Wesley, 2005.
Input image is provided as a texture or as a callback function which
draws the input.
Permission is granted to anyone to use this code as
software for any purpose, including commercial applications.
However, the software is provided 'as-is' without any warranty. | | Keywords | GPU, FFT, GPGPU | | Type | Software | | Year | 2009 | | Publisher | DTU Informatics | | Electronic version(s) | [zip] | | BibTeX data | [bibtex] | | IMM Group(s) | Scientific Computing, Image Analysis & Computer Graphics |
