Abstract :
In this paper we consider the problem of quantifying target distortion in lossy compression using the JPEG2000 Region Of Interest (ROI) option. This approach brings about new problems that need to be addressed, such as automated selection of target regions and ROI preservation parameters. By combining variations of traditional metrics and newly developed segmentation-based image quality metrics, we illustrate several ways to quantify target distortion using ROI preserving compression for various methods including JPEG2000
