Addressing the Interoperability Issues While Using JPEG-XR

摘要

JPEG XR is a new still-image compression standard projected as the successor of the popular JPEG standard. JPEG-XR surely has several advantages over JPEG in terms of higher dynamic range, image tiling capability and higher compression ratios. However it still needs some time before it is actually deployed and accepted by the imaging community. JPEG standard currently has wide-spread usage right from software utilities for viewing and processing images, to support in browsers and to even having dedicated hardware engines to encode and decode JPEG images. In this paper we try to explore the possibilities of interoperability issues in JPEG-XR usage model with reference to handling of non-standard YUV images. When non-standard YUV images are processed by JPEG-XR encoder and decoder, the image viewers cannot display proper images. Based on the simulation results obtained from this study, we show that the proposed approach can overcome the limitation and enable proper images being viewed. In all, we propose three possible approaches that can be followed to make JPEG-XR deployment a user-friendly experience.
