WebAug 23, 2024 · Green's functions are basically convolutions. I'm pretty sure you can express it using e.g. scipy.ndimage.filters.convolve; if your convolution kernel is large (i.e. pixels interact more than with few neighbors) than it is often much faster to do it in Fourier space (convolution transforms as multiplication) and using np.fftn with O(nlog(N)) cost.
