First Claim
Patent Images
1. A method of detecting one or more moving objects, comprising:
- accumulating motion likelihoods from sets of sequential image frames from a sensor scan of the one or more moving objects;
determining one or more regions from the accumulated motion likelihoods, the one or more regions each indicating a probable moving object; and
identifying each of the one or more moving objects from the respective one or more regions that indicate a probable moving object.

Abstract
Moving object detection methods and systems are described. In an embodiment, motion likelihoods are accumulated from sets of sequential image frames which are generated from a sensor scan of one or more moving objects. Regions that each indicates a probable moving object from the accumulated motion likelihoods are determined, and the one or more moving objects are then detected from the respective regions that indicate a probable moving object.

6. A moving objects detection system, comprising:
-
a sensor configured to scan an area that includes one or more moving objects and generate a sensor scan from which sequential image frames are received; a detection application configured to; accumulate motion likelihoods from sets of the sequential image frames; determine one or more regions from the accumulated motion likelihoods, the one or more regions each indicating a probable moving object; and identify each of the one or more moving objects from the respective one or more regions that indicate a probable moving object. - View Dependent Claims (7, 8, 9, 10)

11. A method of detecting a moving object, comprising:
-
receiving a sequence of image frames from a sensor scan; aligning a current image frame with a sequentially previous image frame; generating motion likelihoods from the current image frame when aligned with the sequentially previous image frame; accumulating the motion likelihoods that are generated from the current image frame and from the previous image frame to generate an accumulated motion likelihood; determining region likelihoods for each pixel of the accumulated motion likelihood to detect a region that includes the moving object; and determining a region association from the region likelihoods according to a distance metric, a center of the region association corresponding to a position of the moving object. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
