How I get image from axis for checkbox and get processed

Hello! I have created a simple GUI containing axes,and two edit texts and a browse button. The purpose is when i click on browse button i get the image on axes and filename and pathname are displayed in two edit texts. Code:

[filename pathname ]= uigetfile({'*.jpg';'*.bmp'},'select jpg file'); image = fullfile(pathname,filename ); D=imread(image);

axes(handles.axes1)

imshow(image)

set(handles.edit1,'string',filename);

set(handles.edit2,'string',pathname);

Code is executed successfully. I create two checkboxes containing threshold and equalization and a process button. What i want to do is after displaying the image on the axes I want to get that image for threshold and equalization and when i click on process button the processed images are shown. I tried to do it but i stuck at the point when it comes to getting that image from another object. How should I do it?

The easiest way, is to use the "userdata" of one of your GUI objects, using get & set:

 set(handles.somerandombit,'Userdata',image);
 image = get(handles.somerandombit,'Userdata');

I put it in the threshold checkbox function with but it won't help. Can you tell me what changes I should do?

Do not use image as the name of the variable! You will destroy the built in image() function.
