gpu_convolution | Jeppe Revall Frisvad
| | Abstract | Convolution class for convolution of two RGB images on the GPU.
Convolution: IFFT { FFT(RGB) * FFT(RGB) }
Caution: This operation is expensive. It uses nine 2D FFTs in
five passes and a number of swizzling passes.
Assumes that GLEW is available and has been initialized.
Includes the load_shaders and gpu_fft packages.
Two RGB images in OpenGL textures are expected as input. | | Keywords | GPU, GPGPU, convolution, FFT | | Type | Software | | Year | 2009 | | Publisher | DTU Informatics | | Electronic version(s) | [zip] | | BibTeX data | [bibtex] | | IMM Group(s) | Scientific Computing, Image Analysis & Computer Graphics |
