I have binary image with object skeletons. Image resolution is bigger than my screen, so Matlab have to resized it to fit a screen. But when image is being resized it also interpolated and show as grey-scale image, when I zoom in to check the details skeleton is blurred.

Is there a way to force Matlab to show original image(without resized), when zoomed in?

I try imtool, but didn't help. I only found work around using imcrop but croping image whenever I want check different part of image is relay inconvenient.

Which MATLAB release are you using? One of the recent versions had a bug about how it handled this situation. R2015a I think it was.

I am using R2014b

zoom_image.m

See attached Mathworks demo for how to use a imscrollpanel control. You can display your image with actual pixels, not interpolated, and zoom and scroll as you want.

You're sure you're just zooming, and not using imshow(), right? If so, try calling the Mathworks. I don't know anything about that bug. You can search bug reports here: http://www.mathworks.com/support/bugreports

Yes I am sure. I just modify one line in the demo to read my image not saturn. My university will change Matlab version soon, hopefully it wont be a problem any more. Either way thank you for imscrolpanel demo it will definitely come in handy.
