Doppler-based segmentation and optical flow in radar images
First Claim
Patent Images
1. A computer-implemented method for processing a sequence of images, comprising:
- receiving a sequence of images generated by a radar, each image including a plurality of pixels, each pixel including radial velocity information;
estimating, by a computer, optical flow for the pixels within an image in the sequence of images by using the radial velocity information for the pixels as a constraint, wherein the optical flow is indicative of an object; and
implementing, by the computer, a response at a vehicle based on the object indicated by the optical flow.

Abstract
In an embodiment, a method for processing a sequence of images is provided. The method receives a sequence of images generated by a radar. Each image includes a plurality of pixels. Each pixel includes radial velocity information. The method estimates optical flow for the pixels within an image in the sequence of images by using the radial velocity information for the pixels as a constraint.
