Its a a novel bio-inspired collision detector and its application on a robot. The detector is inspired from LGMD neurons in the locusts, and modeled into an STM32F407 MCU. Compared to other collision detecting methods, we focused on enhancing the collision selectivity in a bio-inspired way that can considerably increase the computing efficiency during an obstacle detecting task even in complex dynamic environment.
That would be a great add-on to the OpenMv libraries.

Re: A Bio-inspired Collision Detector
Hi, for the next release about to come out I finally have optical flow working really well.

Re: A Bio-inspired Collision Detector
Cool, I saw you progress on this and will certainly give it a try.
Did you looked at the paper above?
We dont see much neural network implementation on STM, could be interesting

Re: A Bio-inspired Collision Detector
That algorithm is pretty easy implement. Would you like to give it a shot in C? It seems to require 3 frames in RAM to work but you can easily store that now with the new alloc_extra_fb command.

Re: A Bio-inspired Collision Detector
Yes I can give it a try in C but I would need some guidance from you
Btw this is a more technical paper about the system

Re: A Bio-inspired Collision Detector
If I wrote the input/output part and left you to just write the raw algorithm would that work?
I can make a branch and put the input and output stuff together pretty easily.
A question though, how do you see a img method working? What arguments should it take... what kind of object should it return.

Re: A Bio-inspired Collision Detector
OK I have found a trace of the code here: http://ilab.usc.edu/cgi-bin/secure/view ... ots/LoBot/
I will extract on my github , to test and I will ge back to you

Re: A Bio-inspired Collision Detector
If you have code it's way easier for me to port. A lot less of my time then.
