MATLAB: Task scheduling

You can use this call to start the function "YourFcn", wait for 10 seconds and close Matlab afterwards:

matlab -r "YourFcn; pause(10); exit"

This call can be used in Window's Task Schedular.

Another idea would be to add the exit to the function.

The TimerFcn can run scripts. Simply insert the script name as String as the TimerFcn. But I bet, Matlab will not stay open all the time. The Task Schedular of the operating system is more reliable.

MATLAB: Counting holes in an image

Threshold then call imclearborder() and bwlabel(). Assuming you have dark holes on a bright background:

% Binarize:
binaryImage = grayImage < someValue;
% Remove those touching border
binaryImage = imclearborder(binaryImage);
% Count holes:
[~, numHoles] = bwlabel(binaryImage);
