A new JPEG2000 region-of-interest image coding method: partial significant bitplanes shift

We propose a new region-of-interest (ROI) coding method called partial significant bitplanes shift (PSBShift) that combines the advantages of the two standard ROI coding methods defined in JPEG2000. The PSBShift method not only supports arbitrarily shaped ROI coding without coding the shape, but also enables the flexible adjustment of compression quality in ROI and background. Additionally, the new method can efficiently code multiple ROIs with different degrees of interest in an image.
