Abstract

In many image-coding applications such as web browsing, image databases, and telemedicine, it is needed that only a region of interest(ROI) is transmitted and then reconstructed first before the whole image is transmitted and reconstructed. The Maxshift method has been used as a standard one in this research about ROI coding in JPEG2000. However Maxshift method can process only one ROI, this paper suggests an improved Maxshift method which can process Multiple ROI haying the priority order. In this method, the ROI coefficient which has the high priority order can be moved to upward two bit plane in order to process multiple ROI.
