Line 4: == Multidimensional separable Discrete Wavelet Transform (DWT) == [[Discrete wavelet transform]] is extended to the multidimensional case is using the [[tensor product]] of well known 1-D wavelets. In 2-D for example, the tensor product space for 2-D is decomposed into four tensor product vector spaces as [http://www.uio.no/studier/emner/matnat/math/MAT-INF2360/v12/tensorwavelet.pdf<ref>{{cite web\|title=Tensor products in a wavelet setting\|url=http://www.uio.no/studier/emner/matnat/math/MAT-INF2360/v12/tensorwavelet.pdf\|website=University of Oslo}}</ref>]
