Abstract
A method of event-based down sampling includes receiving multiple sensor events corresponding to addresses and time stamps. The method further includes spatially down sampling the addresses based on the time stamps and the addresses. The method may also include updating a pixel value for each of the multiple sensor events based on the down sampling.
Claims24
A method of event-based down sampling, comprising:
- receiving a plurality of sensor events, each sensor event of the plurality of sensor events corresponding to an address and a time stamp;
- selecting a first sensor event from the plurality of sensor events;
- determining that a second sensor event from the plurality of sensor events is received within a predetermined time of a time stamp corresponding to the first sensor event;
- and
- spatially down sampling the first sensor event and the second sensor event based on the second sensor event being received within the predetermined time.
An apparatus for event-based down sampling, comprising:
- means for receiving a plurality of sensor events, each sensor event of the plurality of sensor events corresponding to an address and a time stamp;
- means for selecting a first sensor event from the plurality of sensor events;
- means for determining that a second sensor event from the plurality of sensor events is received within a predetermined time of a time stamp corresponding to the first sensor event;
- and
- means for spatially down sampling the first sensor event and the second sensor event based on the second sensor event being received within the predetermined time.
An apparatus for event-based down sampling, comprising:
- a memory unit;
- and
- at least one processor coupled to the memory unit, the at least one processor being configured:
- to receive a plurality of sensor events, each sensor event of the plurality of sensor events corresponding to an address and a time stamp;
- to select a first sensor event from the plurality of sensor events;
- to determine that a second sensor event from the plurality of sensor events is received within a predetermined time of a time stamp corresponding to the first sensor event;
- and
- to spatially down sample the first sensor event and the second sensor event based on the second sensor event being received within the predetermined time.
A non-transitory computer-readable medium having program code recorded thereon, the program code for event-based down sampling being executed by a processor and comprising:
- program code to receive a plurality of sensor events, each sensor event of the plurality of sensor events corresponding to an address and a time stamp;
- program code to select a first sensor event from the plurality of sensor events;
- program code to determine that a second sensor event from the plurality of sensor events is received within a predetermined time of a time stamp corresponding to the first sensor event;
- and
- program code to spatially down sample the first sensor event and the second sensor event based on the second sensor event being received within the predetermined time.
