If you had a crack at the code, the community can probably help you out with the bits you got stuck with but I'm afraid no one is going to write a full-blown application/code for you.

if true
% code
end[FileName,PathName] = uigetfile('*.*','Select the image file');

HSV=rgb2hsv(ima);
H=HSV(:,:,1);

V=HSV(:,:,3);
[hca1,hch1,hcv1,hcd1] = dwt2(H,'bior1.3'); [sca1,sch1,scv1,scd1] = dwt2(S,'bior1.3'); [vca1,vch1,vcv1,vcd1] = dwt2(V,'bior1.3');
