1. A computer-implemented method for operating a radar, comprising:
- capturing, at a radar, an image of radar data generated by reflection of a signal from an object in an environment of the radar, the signal being transmitted by the radar;
performing, at the radar, Doppler analysis on the radar data to obtain radial velocity information of the environment;
generating, by the radar, an image of the environment, wherein the image includes a plurality of pixels, each pixel including radial velocity information;
categorizing, by a computer, the plurality of pixels of the image into a plurality of groups of pixels based on radial velocity information of the pixels; and
associating at least one of the groups of pixels with the object.

Abstract
In an embodiment, a method for processing an image is provided. The method receives an image including a plurality of pixels. Each pixel includes radial velocity information. The method categorizes the plurality of pixels of the image into a plurality of groups of pixels based on radial velocity information of the pixels. The method associates at least one of the groups of pixels with an object.
