ABSTRACT:
An illumination-invariant object tracking method and an image editing system using the same are provided. The illumination-invariant object tracking method involves: designating an initial position of an object of interest to be tracked in an image; constructing a probability map for object tracking in consideration of a color ratio of adjacent pixels in the image; and performing Kalman filtering based on the initial position of the object and the probability map. The image editing system based on the illumination-invariant object tracking method includes: a data input unit which receives an image to be edited; an object tracking unit which tracks a target object in consideration of a color ratio of adjacent pixels in the image; an image editing unit which edits and outputs an edited image in a predetermined region of the image, in response to information on the position, size, and boundary of the tracked target object.
