How to seperate LL subband in dwt
Ältere Kommentare anzeigen
I am working on simple dwt2 command. I have shown the LL, LH, HL, HH subband in the figure. Now I need to work on LL subband. So how can I seperate LL out for its further processing

[LL,LH,HL,HH] = dwt2(X,'db1'); % x is input image
figure;imshow(LL); % shows LL subband
