Yesterday Seb-Lee Delisle pointed us via Twitter to this great example of a Flash based real-time face detection. It turns out that already more than half a year ago Ohtsuka Masakazu had been porting the face detection part ofOpenCV to AS3 and added the source code to the Spark project - which is like a Actionscript candy box full of surprises.
So I had a look at the source code and found one feature which I wanted to change: face detection is based on so-called Haar Cascades, simplified one could say that this is a very long list of zones that get checked for certain features in an image. In the orginal version this is an xml file of almost 1 MB size. Because this is so big the xml file gets compressed into a zip file where it fortunately becomes just 100K. So in the orginal version the zip file has first to be loaded and then unpacked and parsed. My consideration was that swfs get zipped anyway, so why not turn the whole xml file directly into a class?
