Abstract

Multiple Region of Interest (ROI) coding is important in applications where some parts of the image are of higher importance than others and need to be encoded at higher quality than the background. The new image coding standard JPEG2000 recommended the Maxshift method to complete ROI coding. However, the drawback of the Maxshift method is that the coefficient bitplanes of all ROIs must be scaled with the same values, which cannot code ROIs according to different degrees of interest. This paper describes a flexible multiple ROI coding scheme called BTShift (Bitplane Twice Shift). The proposed method uses different bitplane scaling strategies between low frequency subbands and high frequency subbands. Experimental results on several state-of-the-art images show that the new scheme does not only support multiple ROI coding according to different degrees of interest, but also can encode the ROIs and background without their shape information. Additionally, BTShift is compliant with the recommended Maxshift method. So we hope the proposed method can be valuable for the remote sensing image compression and medical image coding in the future.
