Abstract

In this paper, we propose a function that provides scalability of image quality on the basis of regions of interest for JPEG2000 coding. Functions of this type are useful in the progressive transmission of images, where the aim is to more quickly decode regions of interest than backgrounds. The proposed method uses the ROI and the SNR layer structure of JPEG2000, and gives better performance than that of conventional methods. Moreover, only a general JPEG2000 Part-1 decoder is necessary to decode the bit-streams generated by the method.
