Region of Interest Coding Based on Multi-Bitplane Interleaving
基于多级位平面交错的ROI图像编码

In many image applications, the coding technology based on Region of Interest(ROI) is very important. With ROI coding technology, the interesting region in image obtains better quality than the region of the background(ROB) at a low compression rate, and the ROB obtains a low level quality at a high compression rate. So the technology solves the conflict between the image quality and the compression rate. General scaling based method and maxshift method are used as the ROI coding technologies in JPEG2000, but there are still limitations in some applications. In this paper, a Multi-Bitplane Interleaving(MBI) method is introduced. The method arranges the bitpalne effectively by using ROI parameter and bitplane parameter. The method allows for arbitrarily shaped ROI coding without transmitting any shape information explicitly to the decoder. And it allows for more flexibility to control the image quality of ROI and ROB. ROIs coding is also allowed for. Because of the characters such as ROIs coding, significant coding of ROI and ROB, the MBI method can greatly meet the coding requirement in different applications.
