Regarding DWT to an Image

Asked by Sriram G on 29 Mar 2013

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 took one of the RADARSAT image as input. <http://imageshack.us/photo/my-images/11/radarsat1jalonsnoirsout.gif/>

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 !
