Abstract

In this paper, we propose an object tracking method using the color information of the image in surveillance network. This method perform a object detection using of adaptive color model. Object contour detection plays an important role in application such as object recognition. Experimental results demonstrate successful object detection over a wide range of object's variation in color and scale. In applications to detect an object in real time, when transmitting a large amount of image data it is possible to find the mode of a color distribution. The specific color of an object is modified at dynamically changing color in image. So, this algorithm detects the tracking area information of object within relevant tracking area and only tracking the movement of that object.Through experiments, we show that proposed method is more robust than other methods under certain ideal situations.

본 논문은 서베일런스 네트워크에서 영상의 색상 정보를 이용한 객체 추적 방법을 제안한다. 이 방법은 적응적인 색상 모델을 이용한 객체 검출을 수행한다. 객체 윤곽선 검출은 객체 인식과 같은 응용에서 중요한 역할을 수행한다. 실험 결과는 색상과 크기에서 객체의 다양한 변화가 있을 때에도 성공적인 객체 검출을 증명한다. 실시간으로 객체를 검출하는 응용 분야에서 대량의 영상 데이터를 전송할 때 색상 분포의 형태를 찾아내는 것이 가능하다. 객체의 특정 색상 정보는 입력 영상에서 동적으로 변화하는 색상에서 자주 수정되어진다. 그래서, 이 알고리즘은 해당 추적 영역 안에서 객체의 추적 영역 정보를 탐지하고 그 객체의 움직임만을 추적한다. 실험을 통해, 본 논문은 어떤 이상적인 상황하에서 제안하는 객체 추적 알고리즘이 다른 방법보다 더 강인한 면이 있다는 것을 보여준다.
