Regarding DWT to an Image

Hi Everybody

Actually am doing project "Ship detection from a satellite based SAR imagery"

The proposed algorithm initially applies the DWT to an Image and applying product to the subbands which is the output of DWT.

So initially i need to apply DWT by means of the dyadic pyramidal algorithm with HAAR coefficient as per the paper.

I wrote the coding as following . . . .Is it right ?

im = imread('radarsat1_jalons_noirs_outship.gif');

[cA,cH,cV,cD] = dwt2(im,'haar');

% finally plotting options

Give your hand Guys !
