Abstract
Provided are a real time multi-object tracking apparatus and method which use global motion, including separating a background and multiple objects from a detected image, recognizing the multiple objects separated from the background; calculating global motion information of the recognized multiple objects, which is information oriented by the multiple objects, and correcting the recognized multiple objects using the calculated global motion information and tracking the multiple objects.
Claims12
A method of tracking multiple objects in real time using global motion, the method comprising:
- separating a background and multiple objects from a currently detected image;
- recognizing the multiple objects separated from the background;
- calculating global motion information of the recognized multiple objects, which is information oriented by the multiple objects;
- and
- correcting the recognized multiple objects using the calculated global motion information, and tracking the corrected multiple objects,
- wherein the recognizing of the multiple objects further comprises:
- setting a support window region by using minimum coordinates and maximum coordinates of a connected component within a topological space from object center coordinate information;
- performing the sampling using multi-scales on the set support window region;
- and
- determining a similarity between objects using information inside of an image block of the set support window region, and recognizing the object.
An apparatus for tracking multiple objects in real time using global motion, the apparatus comprising:
- a background separating unit that separates, by a processor, a background and multiple objects from a detected image;
- an object recognition unit that recognizes, by a processor, the multiple objects separated from the background;
- a global information calculating unit that calculates, by a processor, global motion information of the recognized multiple objects, which is information oriented by the multiple objects;
- and
- an object tracking unit that corrects, by a processor, the recognized multiple objects using the calculated global motion information, and tracks the corrected multiple objects,
- wherein the object recognition unit sets a support window region by using minimum coordinates and maximum coordinates of a connected component within a topological space from object center coordinate information, performs the sampling using multi-scales on the set support window region, determines a similarity between objects using information inside of an image block of the set support window region, and recognizes the object.
