Blur detection for digital images using wavelet transform

1. Harr wavelet transform
using openCV matrix computation.
2. construct Edge-map
Emapi(k,l) = sqrt(HHi(k,l)^2 + HLi(k,l)^2 + LHi(k,l)^2);
We will have 3 Emap
3. construct Edge-max
partition Emap with different window(i=1: 8*8, i=2: 4*4, i=3: 2*2)
4. distingush blur
five rule in paper
