How i can track these dark pixels?

Pixy Software

Hi community,

I’m developing a project with pixy to detect dark objects and keep track of these objects in an environment of high contrast.

Is it possible to select the dark pixels as objects using the algorithm that has pixy?

I believe that granting the ability to detect dark objects would open many applications for the selection and separation of high contrast objects, face detection in bright environments (see image) and many other applications

To do this, is it necessary to modify the firmware?

thanks in advance

Hello Julio,
Currently Pixy doesn’t do this. In general using the darkness of pixels tends to be an unreliable cue because dark pixels are so common. For example, anything in shadow shows up as dark. Shape-based techniques are something we’re working on and hope to add in the future.

We do have a beta version of GCC-compatible firmware. If you’re interested, we can add you to the mailing list.

Hi Edward,

Thanks for the reply, please add me to the mailing list.

Otherwise, is it possible to make a custom version of the firmware to suit my project ?.

Is the firmware source code available?.

Have you contemplated that at some point it can detect dark objects?.

Thanks in advance

Hello Julio,
The source is available!

If you have trouble building the firmware, be sure to post your questions on the mailing list.
