Hi Hardik,

We don’t share our code on the blog as per our policy. If you want to have the code or executable file, you could discuss it with our marking team, see “about” page for details.

Hello Sir,
Thanks for the explanation.But I am still confused.
I am using iPhone 3G.and I want to try out this application.Can you provide me with the sample code or the working code of the same application.I would be very much thanks full to.

How do we add libstdc++ to our project like you specified in Step 9 of the static library instructions?

Hi Stone,

>>actually facedetect alogirthm in opencv is very time consuming and complicated, why not simplify it then you can get fast algorithm on iPhone.

Please refer to our other pages where the same problem is discussed deeply:

1) http://www.computer-vision-software.com/blog/2009/06/fastfurious-face-detection-with-opencv (super fast face detection);
2) http://www.computer-vision-software.com/blog/2009/04/fixing-opencv (face detection for fixed point processor).

I guess it will be interesting for you.

So good tutorial.

If there is one simple tutorial to use opencv static library on iPhone using one simple demo , that will be perfect , I think.

Thanks,

cool to port opencv to iphone.

You are absolutely right. Igor’s 100 ms is for simulator. On real hardware it’s not that good. Finding face on picture 320×240 takes from 300ms to 6 seconds depending on the parameters. But 300 ms is for search window 150×150 – this is a not good way to look for faces in a real life, since lot of faces will be missed.
Things are going better when fixed point version of Viola-Jones is used. In this case it works 2 times faster. Good, but still not perfect.
