## Multiresolution Analysis and Approximation 2

### Here we show a grayscale image given by a 596 by 794 matrix, and its approxamated pictures of level l = 1,2,3,4,5 of the multi-resolution analysis based on the Daubechies 2 wavelet. The level l approximation is a 596 times 2-l by 796 times 2-l matrix.
