Use the uicontrol function, see
doc control
For your example:
global I
global BW
I = imread('ddd.jpg');
Igray = rgb2gray(I);
BW = edge(Igray,'canny');
figure(1)
uicontrol('Style', 'Checkbox',...
'Callback', @canny,...
'String', 'Edge detection'...)
,'Position', [20 20 100 20]...
)
imshow(I)
function canny(src, event)
global I
global BW
if src.Value
imshow(BW)
else
imshow(I)
end
end
