Computing the wavelet transform of an image
First we load the image
Then we set up the parameter of the transform
At last we actually perform the transform
If we do the inverse transform, we get back nearly the original image
Finaly we disp

Linear and non-linear approximation with wavelets
Linear approximation is obtained by keeping M low frequency coefficients and then applying the inverse wavelet transform. Here we take M=n^2/4 by keeping n/2 x n/2 low frequency coefficients.
