I am doing lsb watermarking, in which when i am calculating Normalized correlation, I m getting the above error.
NC = sum(sum(bin_img .* share12))/ sum(sum(bin_img .* bin_img))
where bin_img is original watermark
Cdata 64*64 logical
colormap 2*3 double
And share12 is recovered share (recovered as a part of visual secret sharing)
cdata 64* 128 logical
colormap 2*3 double
when i m trying to resize the share12 as the size of bin_img, I am getting the error.

positive.

You need to show us the relevant part of the code where imresize() is being called. It's also giving you a very good idea of what the problem is from the error message.
