You need to either add a callback function to the image/figure to respond to user key presses or mouse clicks, or you could add something like getpts.
I would add two buttons to the figure, one states "Next" and the other "Store", and implement callbacks on those buttons (you could even add a previous).
Here is a quick example - I would implement the callbacks a bit differently and not have the while loop at the end, but it illustrates the point:
function Selected = TestFun
clf;
I = randn(100, 100, 10);
count = 1;
Selected = [];
h = imagesc(I(:, :, count));
hb1 = uicontrol('Style', 'PushButton', 'String', 'Next', ...
'Callback', @NextBtnCB);
hb2 = uicontrol('Style', 'PushButton', 'String', 'Store', ...
'Callback', @StoreBtnCB);
hb1.Position(2) = hb2.Position(2)+1.1*hb2.Position(4);
while isempty(Selected)
pause(.1);
end
function NextBtnCB(src, evnt)
if count<size(I, 3)
count = count + 1;
h.CData = I(:, :, count);
end
end
function StoreBtnCB(src, evnt)
Selected = count;
end
end
