MATLAB: How to capture image in gui

gui

I have created gui with two axes and one pushbutton. I use axes1 to view live video from webcam and i don't have problem with it. But i don't know how to capture the image from axes1 and display the image in axes2.

Best Answer

Try this:

axes(handles.axes1); % Switch focus to axes1.
theImage = getimage(); % Snag the image out of axes1.
axes(handles.axes2); % Switch focus to axes2.
imshow(theImage); % Place theImage into axes2.

If you want to make more compact, you could skip axes() and pass the axes handle into getimage() and imshow() but then to get other things, like title() etc., to appear on the correct axes you'll have to pass the handles into those functions too. If you call axes() things like titles will appear on the current axes (the one you just passed into axes() function).

You can try this:

image1 = get(handles.axes1, 'CData');
imshow(image1, 'Parent', handles.axes2);

MATLAB: Passing an axes handlle to a function

function rescaleImage(handles,str)
%Get image on axes1
axes(handles.axes1)
image1 = getimage(handles.axes1);
%Create handle for new placement of image
%Use str argument to pass the axes handle
imshow(image1,[], 'Parent', handles.(str))

and instead of passing 'handles.axes3' pass 'axes3'
