• Program Listing for File dvs_noise.h

Detailed Description

The DVS noise filter combines a HotPixel filter (high activity pixels), a Background-Activity filter (uncorrelated events), and a Refractory Period filter (limit event rate of a pixel). The HotPixel and Background-Activity filters reduce noise due to transistor mismatch, the Refractory Period filter can reduce the event rate and is efficient to implement together with the Background-Activity filter, requiring only one pixel memory map for both. Please note that the filter is not thread-safe, all function calls should happen on the same thread, unless you take care that they never overlap.
