Blob Outlines

Postby Isperia » Tue Aug 11, 2020 5:23 pm

Hi,
is it possible to find the outline of a blob? ie, not the bounding box, but rather all of the outermost pixels in the blob?
Thanks

We don't store the contour of the blob. Our API was built on supporting extremely low memory Microcontrollers. As such, storing that would be a challenge. I.e. for the M4 core it would be a huge amount of RAM per blob. We had barely more than 14KB free for the heap there.

On the H7 however, this isn't really a big deal anymore though. It would be possible. However, it's not implemented.
Nyamekye,
