Foil 15 Mathematical Structure of Discrete Wavelet Transform-II
From HPDC95 Compression Presentation HPDC95 Pentagon City -- August 1,1995. by Roman Markowski and Geoffrey Fox * Critical Information in IMAGE
The solution of these 4 equations is:
The Smoothing Filter H is the average:
The detail is contained in operator G:
First step produces N/2 smooth and N/2 detail values.
Then we take N/2 smooth values and repeat step getting
N/4 smooth and N/4 further detail results at double spatial resolution
This recursively leads to pyramid algorithm
