Abstract
A signal processing method includes obtaining an image signal and a first event signal that are of a target scene, where the first event signal is an event signal in a frame format or a stream format; performing time-dimension and/or space-dimension format conversion on the first event signal, to obtain a second event signal, where the second event signal is an event signal in a frame format; and fusing the second event signal and the image signal, to obtain a fused signal.
Claims20
A method comprising:
- obtaining an image signal and a first event signal that are of a target scene, wherein the image signal indicates luminance information of a plurality of pixels corresponding to the target scene within an exposure time period, wherein the first event signal indicates motion information of the plurality of pixels within the exposure time period, and wherein the first event signal is in a frame format or in a stream format;
- performing at least one of time-dimension or space-dimension format conversion on the first event signal to obtain a second event signal, wherein the second event signal is in the frame format, and wherein a first resolution of the second event signal is equal to a second resolution of the image signal;
- and
- fusing the second event signal and the image signal;
- to obtain a fused signal.
An apparatus comprising:
- a memory configured to store instructions;
- a communication interface is-configured to receive, from a signal processing device, an image signal and a first event signal that are of a target scene, wherein the image signal indicates luminance information of a plurality of pixels corresponding to the target scene within an exposure time period, wherein the first event signal indicates motion information of the plurality of pixels within the exposure time period, and wherein the first event signal is in a frame format or in a stream format;
- and
- one or more processors coupled to the memory and the communication interface, and configured to execute the instructions to cause the apparatus to:
- perform at least one of time-dimension and/or space-dimension format conversion on the first event signal to obtain a second event signal, wherein the second event signal is in the frame format, and wherein a first resolution of the second event signal is equal to a second resolution of the image signal;
- fuse the second event signal and the image signal to obtain a fused signal;
- and
- send the fused signal to the signal processing device through the communication interface.
A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable storage medium, wherein the computer-executable instructions when executed by one or more processors of an apparatus, cause the apparatus to:
- obtain an image signal and a first event signal that are of a target scene, wherein the image signal indicates luminance information of a plurality of pixels corresponding to the target scene within an exposure time period, wherein the first event signal indicates motion information of the plurality of pixels within the exposure time period, and wherein the first event signal is in a frame format or in a stream format;
- perform at least one of time-dimension or space-dimension format conversion on the first event signal to obtain a second event signal, wherein the second event signal in the frame format, and wherein a first resolution of the second event signal is equal to a second resolution of the image signal;
- and
- fuse the second event signal and the image signal, to obtain a fused signal.
