I have image, and I want to do up sampling. First of all I need to plug zeros between pixels such that [1,2,3] transforms to [1,0,2,0,3]. Can anyone tell me how to do it without using paddarray
and without using for
loops?
Thank you in advance!
Something like this?:
B=zeros(size(img)*2);
B(1:2:end,1:2:end)=img;
However there are ways of up-sampling in matlab without having the need of doing it by hand, for example interp2
