Hello I have an image and I did resampling on it
( NI = imresample([0.5,0.5],I,[1,1],'linear');)
can I find old pixel in first image from resampled image? in fact I want to know what was the pixel NI(1,1) in image I?

imresample is not in base MATLAB or the Image Processing Toolbox. It's a pretty good bet though that the (1,1) pixel has the same value in both images. Of course it is trivial to check that:
difference = abs(double(oldImage(1,1)) - double(newImage(1,1)))
It probably doesn't move.

Maybe you should use imresize() instead. Would that do what you need to do, or is there something special about imresample? Not from what I can see. It appears to be only for those unfortunate souls who do now have the Image Processing Toolbox.
