Doesn't scikit-image has a 2d convolution function like cv2.filter2D in OpenCV which enables convolution of an image (or any numpy array) with custom kernel ?
Convolution can be done in Fourier space, especially if the kernel is large ... I do that often, especially on nvidia GPU where FFT is for free. I will have a trainee working on more generic 2D convolutions using OpenCL, this summer. Cheers, -- Jérôme Kieffer <google@terre-adelie.org>
