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." }
