Hello.
I built a GUI for Image Restoration.
I want to let the user use the imcontrast tool:
http://www.mathworks.com/access/helpdesk/help/toolbox/images/imcontrast.html

What I couldn't do is getting back the adjusted values after the user applied the his choice using the imcontrast tool.

Let's say I have an Image - I.
I open an a window displaying it:

imshow(I, []);

Then letting the user play with the imcontrast tool:

imcontrast;

Now I want to get back the adjusted Matrix.
How can I do that?

Thanks.

get() the CData property of the image after you have adjusted its contrast.

Hello.
Thanks for the answer.
The problem is I only have the Figure handler.
How can I extract the image object handler out of the figure handler?

Thanks.

ImageHandle = findobj(FigureHandle, 'Type', 'image');
