Wavelet decomposition of an image

[LL3,HL3,LH3,HH3]=dwt2(LL2,'haar');

LL3,i got it as 1.0e+003 * and values as 0.8241 0.6743 0.3463 0.1771 0.2440 0.3396 0.2764 0.6983 0.2599 etc..

When i gave B=floor(LL3); i got values as 824 674 346 177 244 339 276 etc.

Is this correct? Kindly help me.

Give the command

format long g

and then display LL3 again.

[Pooja]

normally what will be the o/p values of LL3 ?

Those look about right. See the scaling on the sample haar graph in http://www.mathworks.com/matlabcentral/fileexchange/24092-objectsfaces-detection-toolbox/content/fdtool_release/html/demo_haar.html
