APPARATUS FOR TRACKING AN OBJECT USING A MOVING CAMERA AND METHOD THEREOF
First Claim
1. An apparatus for tracking an object, comprising:
- a dynamic area extracting unit that extracts an object to be tracked from an image frame collected through an image collecting apparatus;
an object modeling unit that models the object to be tracked extracted through the dynamic area extracting unit to calculate the color distribution of the object to be tracked; and
an object tracking unit that calculates the color distribution of a next image frame collected through the image collecting apparatus, after calculating the color distribution of the object to be tracked, and calculates a posterior probability that each pixel belongs to the object to be tracked in the next image frame based on the calculated color distribution of the next image frame and the color distribution of the object to be tracked to track the object to be tracked.

Abstract
Provided is an apparatus for tracking an object, including: a dynamic area extracting unit that extracts an object to be tracked from an image frame collected through an image collecting apparatus; an object modeling unit that models the object to be tracked extracted through the dynamic area extracting unit to calculate the color distribution of the object to be tracked; and an object tracking unit that calculates the color distribution of a next image frame collected through the image collecting apparatus, after calculating the color distribution of the object to be tracked, and calculates a posterior probability that each pixel belongs to the object to be tracked in the next image frame based on the calculated color distribution of the next image frame and the color distribution of the object to be tracked to track the object to be tracked.

11. A method for tracking an object, comprising:
-
extracting an object to be tracked from an image frame collected through an image collecting apparatus; calculating the color distribution of the object to be tracked by modeling the extracted object to be tracked; calculating the color distribution of the object to be tracked and then calculating the color distribution of a next image frame collected through the image collecting apparatus; and calculating a posterior probability that each pixel belongs to the object to be tracked in the next image frame based on the calculated color distribution of the next image frame and the color distribution of the object to be tracked to track the object to be tracked. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
