Does anyone know how to do this in Octave or some other free software rather than Matlab?

- kwhitefoot 2y agoIn case anyone else wants to know the solution is: >> woman = imread("~/Downloads/woman-with-cat.png"); >> colormap('gray'); >> imagesc(woman, [0 255]); >> pkg load signal >> cat = dct2(woman); >> pkg load image >> imagesc(imsmooth(cat, "Gaussian", 1), [-4 4]); dct2 is unimplemented in the image package but exists in the signal package.
