Enhance your images! Create beautiful special effects!
IMADJUSTGUI launches an interactive, uicontrolled app for use with the Image Processing Toolbox function IMADJUST.
Interactively modify an image using sliders to modify the pixel mappings, either en masse, or (for RGB images)plane-by-plane.

See HELP IMADJUST for details.

Allows exporting of the modified image, and generates a function handle with which to recreate the modifications.

@curoi,
gobjects was added to MATLAB in R2013a. Upgrading will address the issue. Alternatively, in older versions you should be able to replace 'gobjects' with 'zeros'; I think it will work.

Not sure about anyone else but I get the following error when I try to run the .m file or the app:

Undefined function 'gobjects' for input arguments of type 'double'.

Error in ImageAdjuster (line 132)
histax = gobjects(6,1);

How do you fix this?

@Nikita:
I am not able to reproduce that behavior (though I am seeing other unexpected, unwelcome behavior when I call the UI from another UI). Honestly, I never tried calling it from another GUI, and I'm not sure what is going on. Can you tell me what version of MATLAB you're using, and what OS? How are you calling it from your GUI? (Can you show a code snippet?)
Thanks,
Brett

Hi there,

Hi I tried to call this GUI from another GUI, but when it opens up, the image flashes for a second and then disappears, I also see an error with something like Error using handle.handle/set
Invalid or deleted object.
Any idea what I'm doing wrong?

Bravos! This saves my life! Love the user-friendly output as well!!!

@Nathan,
There's a radio button that says "Process planes individually." If you select that, it enables plane-by-plane adjustment. Is that not what you're looking for?

I really like this. I wish you made it do imadjust on all 3 channels separately. That way you could tweak the color of an image pretty easily. Let me know if you can add this.

For use on 2008a I modified ImadjustGUI.m:
- Replaced (non-logical) tildes with variable 'dummy'.
- Added to line 76:
set(adjfig,'HandleVisibility','on')
- Added to line 86:
set(adjfig,'HandleVisibility','callback')

Works as promised.

Updates

1.10.0.1

Updated license

1.10

Minor fixes, updates to graphics, readiness for R2014b.

1.8

Fixed a bug that disallowed working with grayscale images.

1.7

Now allows loading an image from file or from workspace variables. Also, I added "Auto-Adjust" button to add stretchlim-based starting point.

1.6

Many improvements, including: better loading of new images (from file or workspace); addition of an auto-adjust button; incorporation of improved ExpandAxes (which now allows for right-click exporting of images); better support for App version.

1.5

Updated to include an App file for R2012b.

1.1

This is a complete re-write of my old INTENSITYADJUST file. This is a much better implementation, and now allows independent modification of RGB planes.
