AS3 Version of OpenCV for Facial Detection, Web Cam Object Detection, Head Tracking, 3D Library Integration and more with Open Computer Vision Library for Flash
Libspark from Japan is a treasure trove of great flash advancements, they seem to realize the great things that can come from porting in existing solid libraries from C/C++ etc into flash and have been scoring lately including augmented reality in flash porting the ARToolkit to FLARToolkit. Recently a port of openCV for as3 called Marilena was found and it is for object detection and decent facial recognition (it is a computer vision library from intel) considering the processing power needed to do this.
Face Detection: Here is the sample included with Marilena showing facial detection on an image.
Lots of recent action has blown up on this front from Mr doob, quasimondo (optimizing the Marilena classes for better performance) and Boffwswana. Also there is a kit called deface by sshipman that is the first foray into this a year ago doing similar things but it was just a bit before it’s time and a bit slow in previous versions of flash, it performs decent now in this sample. Flash 10 performance of the AVM2 and future directions with Alchemy will lead to more interesting stuff just like this.
Boffswana example of head tracking Johnny Lee Wii style with only a webcam and flash, no wiimote needed since it uses facial detection to check where you are and how close you are in the screen and then moves accordingly.
This is stemming from the recent explosion of the FLARToolkit and augmented reality in flash as well as the gimmicks used by Nintendo with the wii and Johnny Lee’s great head tracking advancements. Porting great libraries to flash seems to be the phase we are entering now judging by the recent excitement around Adobe Alchemy and the LLVM along with the lead from the libspark.org contributors. We have also seen this heavily last year in ports of Box2D for 2d physics and other toolkits using established working code and porting that to flash now that is is mostly capable of handling the performance.
OpenCV (Open Computer Vision Library by Intel) is quite a powerful platform that allows you to do all this and now it is available in flash. There are other great libraries for nearly all platforms now. I have done some previous work with Aforge which is also a port of OpenCV mainly for motion detection. This was always around but not until the recent performance updates and the innovation that has come with Alchemy and the thinking that goes along with that (porting in libraries to flash from C/C++ etc), has allowed this to flourish in flash and thus the web.
The amazing new things we can do with flash by porting in existing libraries is only going to get more intense as alchemy and flash 10 are even more mainstream. It is almost as if Flash will eventually just become a web renderer and simplified front end to many great toolkits that exist in more native environments like C/C++ but with the speed and distribution access of the web with Flash. Exciting times ahead.
