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 !
