Abstract
An algorithm is presented for calculating the 2D wavelet transform of a Toe plitz matrix. The algorithm exploits the special form of the Toeplitz matri x in order to reduce the number of operations required. More specifically, it is shown that the number of 1D wavelet transformations that are necessar y to carry out a sub-band decomposition can be reduced to eight.
