Time Surface
One method of representing event camera data in which each pixel records the timestamp of the most recent event, converted into a feature map through an exponential decay kernel, preserving temporal information and being sensitive to motion.
Timeline (last 90 days)
In time surface representation, each pixel records the timestamp of the most recent event, forming a time surface map that preserves temporal information and is sensitive to motion.
Event frames suit object detection in static scenes, time surfaces suit motion estimation, and voxel grids are used for tasks requiring fine spatiotemporal information.
