Face Detection with PixyCam (1 or 2)

Hi, can we detect face with PixyCam 1 or 2?

My application involves detecting, not recognizing, any face. I have used OpenMV M7 module and it is able to do it. But the camera/lens size is too much for my application.

Newly released PixyCam 2 is 0.6" in depth and that is acceptable for me.

Thanks in advance.

Hello Muneeb,
Pixy2 does not support face detection. (sorry)

Thank you Edward.

Any plan to support it in near future? Or anything I can explore to achieve it by myself?

As I understand it, engineering experimented with implementing face detection a while back, but they were unable to get it working satisfactorily with Pixy’s limited resources (mostly memory, I think). So, there are hardware limitations and we won’t be pursuing it in future.

Sorry to disappoint!

Hi Muneeb,
This is the popular approach:

Pixy can run a haar classifier, but the accuracy is mediocre. We punted on the project, but we’ll log your message as a feature request.

We also have the firmware SDK if you’d like to get your hands into the low-level code:
