METHOD AND APPRATUS FOR TRACKING OBJECTS
First Claim
1. A method for tracking an object in an object tracking apparatus, the method comprising:
- receiving an image frame of an image captured by the image acquisition apparatus;
detecting a target, a depth analogous obstacle with a similar depth to the target and an appearance analogous obstacle with a similar appearance to the target from the image frame;
tracking the target, the depth analogous obstacle and the appearance analogous obstacle that are detected;
when the detected target overlaps the depth analogous obstacle, comparing the variation of tracking score of the target with that of the depth analogous obstacle;
continuously tracking the target when the variation of tracking score of the target is below that of the depth analogous obstacle and processing a next frame when the variation of tracking score of the target is above that of the depth analogous obstacle; and
re-detecting the target.

Abstract
A method for tracking an object in an object tracking apparatus includes receiving an image frame of an image; and detecting a target, a depth analogous obstacle and an appearance analogous obstacle; tracking the target, the depth analogous obstacle and the appearance analogous obstacle; when the detected target overlaps the depth analogous obstacle, comparing the variation of tracking score of the target with that of the depth analogous obstacle. Further, the method includes continuously tracking the target when the variation of tracking score of the target is below that of the depth analogous obstacle and processing a next frame when the variation of tracking score of the target is above that of the depth analogous obstacle; and re-detecting the target.

10. An apparatus for tracking an object, the apparatus comprising:
-
an input unit configured to receive an image frame of an image captured by an image acquisition apparatus; a detection unit configured to detect a target, a depth analogous obstacle with a similar depth to the target, and an appearance analogous obstacle with a similar appearance to the target from the image frame; a tracking unit configured to track the target, the depth analogous obstacle and the appearance analogous obstacle that are detected; a comparison unit configured to compare the variation of tracking score of the target with that of the depth analogous obstacle when the detected target overlaps the depth analogous obstacle; and an overlap analysis unit configured to continuously track the target when the variation of tracking score of the target is below that of the depth analogous obstacle and progressing to a next frame when the variation of tracking score of the target is above that of the depth analogous obstacle. - View Dependent Claims (11, 12, 13)
