Method and apparatus for performing motion analysis on an image sequence
First Claim
Patent Images
1. A method for performing motion analysis on a sequence of images, where said sequence of images captures a plurality of objects each moving along a trajectory in an imaged area, said method comprising:
- extracting motion information for each of said plurality of objects contained in said sequence of images; and
determining spatial patterns from said extracted motion information.

Abstract
A method and concomitant apparatus for performing motion analysis on a sequence of images is disclosed. Initially, the sequence of images is received from a video source. The sequence of images captures a plurality of objects each moving along a trajectory in an area imaged by the video source. Motion information is extracted from the sequence of images for each of the plurality of objects. Spatial patterns are then determined from the extracted motion information.

15. A method for displaying motion information of objects contained in a sequence of images, the method comprising:
-
performing a query on a plurality of spatial patterns stored in a database, where each of said plurality of spatial patterns comprises a route determined from a trajectory common to at least two objects moving in an imaged area captured in said sequence of images;
determining a trajectory satisfying at least one constraint specified in said query; and
displaying said determined trajectory on a user interface.

16. A system for performing motion analysis on a sequence of images, the apparatus comprising:
-
a motion extraction system for receiving said sequence of images capturing a plurality of objects each moving along a trajectory, and extracting motion information for each of said plurality of objects over said sequence of images; and
a motion mining system for determining spatial patterns from said extracted motion information, where said spatial patterns comprise a route determined from said trajectory common to at least two objects. - View Dependent Claims (17, 18, 19, 20, 21)
