Scipy dct2

WebFor norm="ortho" both the dct and idct are scaled by the same overall factor in both directions. By default, the transform is also orthogonalized which for types 1, 2 and 3 means the transform definition is modified to give orthogonality of the IDCT matrix (see dct for the full definitions). ‘The’ IDCT is the IDCT-II, which is the same as the normalized DCT-III.
