Recently, a method for correspondence search between two images, which is called POC (Phase-Only Correlation) method, has been proposed. The coarse-to-fine technique based on the POC method can hierarchically search corresponding points from coarser images to finer images and it can contribute to a high accuracy and high speed tracking of the moving object. In this paper, we propose an algorithm which implements an automatic detection of the ROI region using the tracking technique based on the POC method. By applying both the coarse-to-fine technique and the space scalability in DWT, we can implement a high accurate and efficient tracking of the moving object. In the proposed method, DWT coefficients of an image which are obtained from an encoder of JPEG2000 are used for the tracking of the moving object.
