hello Experts,
I am getting an error in this code which is shown on this image. Plus I assigned b=1 but it is showing 393.
Any help would be appreciated.

Hello marie.
Without the full code, it is difficult to know exactly what is happening.
From what i can gather, the issue is the argument passed to the array dct2. So, whatever watermarked_image() is returning, is exceeding size(dct2).
If you post more code, and post it as text (not an image), then I can run it myself, and will be able to help a lot more.
Hope this helps.
I managed to get an output, by changing the following:
% Around line 44
ind_2 = b:b+blocksize-1;
ind_1 = a:a+blocksize-1;
dct_block=dct2(watermarked_image(ind_1,ind_2));
Just switch the arrays around. If this inverts your image, I am not sure, but this way the sizes matched up.
Also, trying to write to a file named: dct_wa:ermarked_lenal.jpg caused some issue. I am not sure why.
So, I changed the file name. (Around Line 88)
I hope this helps
