Hi :);
Is there someone who can explain to me why when I apply Db3 on my Test image which contains a hole it shifts especially when I augment in the Level from 2 to 5
and when I apply the Haar wavelet the edges of the hole becomes so blur every
time I augment the Level ?????
I'm really confused!!!Why
