Abstract
Regions Of Interest (ROI) image coding is one of the most significant features in JPEG2000 for network applications. In this paper, a new approach for ROI coding so-call Up-Down Bitplanes Shift (UDBShift) is presented. This new method separates all bitplanes into three parts: Important Significant Bitplanes (ISB), General Significant Bitplanes (GSB) and Least Sig-nificant Bitplanes (LSB). The certain number bitplanes of ROIs are up-shifted to ISB based on different degrees of interest of every ROI. Then, partial BG bitplanes are downshifted to LSB according to encoding requirement. Finally, The residual significant bitplanes of ROIs and BG that are saved in GSB are not shifted. Simulation results show significant improvement in reduction of reduction of transmission time and enhanced flexibility at the expense of a small complexity. Additionally, it can support arbitrarily shaped multiple ROI coding with different degrees of interest without coding the ROI shapes.
