EKLT leverages the complementary of event cameras and standard cameras
to track visual features with low latency in the blind time between two
frames. Event cameras are novel sensors that output pixel-level
brightness changes, called "events". They offer significant advantages
over standard cameras, namely a very high dynamic range, no motion blur,
and a latency in the order of microseconds.
By leveraging the generative event model EKLT is the first method that
combines raw intensity measurements and events directly and in a
principled manner, based on a generative event model within a
maximum-likelihood framework. As a result, our method produces feature
tracks that are more accurate than the state of the art, across a wide
variety of scenes.
