A Format for Digital Preservation of Images: A Study on JPEG 2000 File Robustness

Digital preservation requires a strategy for the storage of large quantities of data, which increases dramatically when dealing with high resolution images. Typically, decision-makers must choose whether to keep terabytes of images in their original TIFF format or compress them. This can be a very difficult decision: to lose visual information though compression could be a waste of the money ex...

JPEG 2000 still image coding versus other standards

JPEG 2000, the new ISO/ITU-T standard for still image coding, is about to be finished. Other new standards have been recently introduced, namely JPEG-LS and MPEG-4 VTC. This paper compares the set of features offered by JPEG 2000, and how well they are fulfilled, versus JPEG-LS and MPEG-4 VTC, as well as the older but widely used JPEG and more recent PNG. The study concentrates on compression e...

JPEG 2000 vs. JPEG in MPEG Encoding

The MPEG-2 standard is the most used codec for video compression. This paper investigates the consequence of replacing the JPEG core system of the MPEG-2 video codec by a progressive image codec, specifically JPEG 2000, so creating a video codec (VC) that can match any desired bit rate. The quality of compressed video sequences between MPEG-2 and VC is compared. Results show that our codec impr...
