I am working on Live image processing. And want to show processed image as fast as I can.

finalImage = imshow(im);
for i=1:dataLength
  tic
  zoomIm = imTransform(im);    % Main Image Transforming function
  title(['CPU-Elapsed Time: ' sprintf('%0.3f Sec', toc)])
  set(finalImage,'CData',zoomIm);
  %drawnow
  pause(0.0001)
end

I am not using drawnow, because it takes much time.

But is there any other out of the box efficient way to processes and show live images?

If you have the nocallbacks flag, does you exit callback still work?
