Abstract
A technology is described for pixel frequency filtering for event cameras. An example of the technology can include receiving events representative of changes in brightness detected by a pixel in a pixel array included in the event camera, tracking a number of event sign transitions that occur within a defined time window, determining that the number of event transitions corresponds to an event transition frequency, and allowing the events generated by the pixel to be output from the event camera.
