From TIFF to JPEG 2000? Preservation Planning at the Bavarian State Library Using a Collection of Digitized 16th Century Printings
Studies and user reports claim JPEG 2000 to be – or at least will become – the next archiving format for digital images [1]. The format offers new possibilities, such as streaming, and reduces storage consumption through lossless and lossy compression [2]. Another often claimed advantage of JPEG 2000 is that the master image can possibly serve as the access copy as well, and thus replace derive...

متن کاملJPEG 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...
متن کاملAssessing the Ocr Degradation in the Generation of Jpeg, Png, and Tiff Files from Adobe Pdf
Adobe Portable Document Format is de facto standard today due to its widespread use. One of the features of Adobe pdf is that it allows exporting documents as images that may be saved in JPEG, PNG, and TIFF formats. This paper uses an OCR platform to quantitatively assess the quality of these image file
متن کاملSecure JPEG 2000-JPSEC
The Joint Photographic Experts Group (JPEG) has recently rolled out a new still image coding standard called JPEG 2000. This standard integrates an efficient image compression scheme with functionalities required by multimedia applications, such as progressiveness up to lossless coding, region of interest coding, and error resiliency. Security is a concern in many applications, and therefore al...
