Paper Abstract

Recently, developing of image processing method which enables to track to moving objects on time series images taken by a fixed camera is one of important subjects in the field of machine vision. Here, we try to consider influences by change in brightness and change of region caused by moving objects, respectively. In this paper, we introduce a new tracking method which can be reduced the influences by those changes. First, we use Radial Reach Filter in order to detect the moving objects. In addition, the moving objects can be tracked by an image processing based on information obtained by applying RRF and block division. Further, we propose a method in the case that changes size of moving object by time progress. Finally, through experiments we show the validity of our proposed method.
