Method of operating dynamic vision sensor system

A method of operating a dynamic vision sensor system, the method comprising:

• obtaining original image data including a plurality of image pixels corresponding to a plurality of dynamic vision sensor (DVS) pixels;
• classifying the plurality of image pixels into first image pixels having a first pixel value and second image pixels having a second pixel value different from the first pixel value;
• grouping the first image pixels into a plurality of pixel groups;
• selecting a plurality of effective groups from the plurality of pixel groups by determining the number of first image pixels in each of the plurality of pixel groups, determining an arrangement shape of the first image pixels in each of the plurality of pixel groups, and selecting a pixel group as an effective pixel group based on the number of first image pixels and the arrangement shape;
• and
• determining a movement speed and trajectory of an object using the plurality of effective groups.

A method of operating a dynamic vision sensor system, the method comprising:

• obtaining image data having a plurality of image pixels corresponding to a plurality of dynamic vision sensor (DVS) pixels configured to detect a change in light caused by movement of an object;
• obtaining a plurality of pixel groups by grouping first image pixels from among the plurality of image pixels, wherein the first image pixels correspond to DVS pixels that detected a change in light over a predetermined period;
• and
• selecting a plurality of effective groups, each effective group representing a position and a shape of the object at each of a plurality of time points from the plurality of pixel groups, and determining movement of the object using the plurality of effective groups.
