Abstract: A method produces a compressed sequence of events stored in a memory, originating from an event-based camera, the sequence comprising a first run-length code representing timestamps of the sequence of events; and subsequent compressed codes including one of: (i) a second run-length code representing first coordinates of the sequence of events, at least one dictionary code representing second coordinates of the sequence of events, and data representing polarities of the sequence of events; (ii) a second run-length code representing first coordinates of the sequence of events, a number of bit-packed fields, each representing a second coordinate and polarity pair of the sequence of events; or (iii) a number of bit-packed fields, each representing a first and second coordinate and polarity triplet of the sequence of events.
