How can I change the figure in which I'm drawing with imfreehand?

2 views (last 30 days)
I segment an image after specifying some segmentation seeds via imfreehand, then I get the segmented image on a new figure and I want to redraw some seeds on this new figure. How can I make the new calls to imfreehand be directed to the new figure and not the previous one?

I used this:
figure('name', 'image to segment'), imshow(imdata,[]);
h = gcf
%...
%do segmentation
figure(h), imshow(segmented_foreground, []);

The documentation of imfreehand reveals, that the handle of axes to operate in can be specified as first input.

The documentation is insufficient for me. It doesn't specify how one gets the hparent that points to a figure.

Let's say that you're using GUIDE and you have two "axes" controls on your GUI called axes1 and axes2 - this means that the "tag" property for those controls is axes1 and axes2. Then before you call imfreehand, simply call axes to switch focus (switch the gca which is the current axes):
axes(handles.axes2);
handleToDrawing = imfreehand();
Or pass it in
handleToDrawing = imfreehand(handles.axes2);

Replace handles.axes2 with whatever the handle to your axes is - the one you got from uicontrol() when you called that.
