If anyone is interested, I ported the image processing portion of this code to Python. http://www.chiefdelphi.com/forums/sh...d.php?t=112866

if it's not too much to ask, could someone please walk me through how to run the code with test images? I put the argument (a string with the path to my test image) in the arguments field of the project properties, run window. but when i run it in netbeans, i get the following errors in the netbeans output window. i guess it is trying the run the smartdashboard somehow, as it is supposed to, but how do I make this work for test images.

It looks like some of the internal changes to SmartDashboard for 2013 have broken stand-alone operation. Never fear, here is how to fix it:

Add the line:

DashboardFrame frame = new DashboardFrame(false);

...inside the main method before creating the DaisyCVWidget.
