FHROI: Interactively specify 2D freehand ROI
Overlays an imfreehand ROI on an image.
Gives the ability to tweak the ROI by adding and
subtracting regions as needed, while updating
the ROI boundaries as an overlay on the image.
Returns a logical matrix of the same size as the
bwMask = fhroi([axHandle])
axHandle: handle to axes on which to operate (optional)
bwMask: ROI mask as logical matrix
I = rand(20) + eye(20);
imshow(I, , 'Colormap', hot, 'initialMagnification', 1000);
bwMask = fhroi;
