Moving Object Detection and Tracking Based on the Contour Extraction and Centroid Representation

Abstract

This chapter presents a novel approach for moving object detection and tracking based on the Contour Extraction and Centroid Representation (CECR). Firstly, two consecutive frames are read from the video and they are converted into gray scale. Next, the absolute difference is calculated between them and the result frame is converted into binary by applying gray threshold technique. The binary frame is segmented using contour extraction algorithm. The centroid representation is used for motion tracking. In the second stage of experiment, initially object is detected by using CECR and motion of each track is estimated by kalman filter. Experimental results show that the proposed method can robustly detect and track the moving object.
