f = imread('Region_of_interest.bmp');
imshow(f)
wname = 'sym4';
[CA,CH,CV,CD] = dwt2(X,wname,'mode','per');
subplot(211)
imagesc(CV); title('Vertical Detail Image');
subplot(212)
imagesc(CA); title('Lowpass Approximation');
Sir, kindly help me.
thanks and regards
Debarpita Chaudhuri.

dwt2() is part of the Wavelet toolbox. You would need to have that installed and licensed.
