Dynamic Vision Sensor

I thought it could be inspiring for the development of sensors (more even for sensorimotor integration):

No influence of learning based on the permanence of proximal connections

We have a DVS camera in our lab, it’s very intriguing, especially the incredibly high effective framerates. One potential caveat is that the output is unbelievably noisy:

Very noisy, but doesn’t look too noisy to to SDR comparison operations successfully!

@juanhorta, I recently started tinkering with this which seems more valuable the more I think on it, thanks for the idea. HTM models change in input. These sensors abstract the change in visual data in a sparse way.

For those without the budget for a real DVS, this library emulates the output of a DVS using a normal frame based camera or single images and movies as input.
