JPEG-HDR 1.1
 
Category(s):Utilities > File Compression
  
Summary:JPEG-HDR provide HDR image file compression overcomes the file size problem. Previously, typical HDR images would require many megabytes of storage but by applying BrightSide' JPEGHDR encoding, the size can be reduced to kilobytes. Compression of up to 25:1 can be achieved while maintaining excellent image quality and the final JPEGHDR image file is often only about 10% larger than a typical low dynamic range JPEG image.

Application Description
 
JPEG-HDR provide HDR image file compression overcomes the file size problem. Previously, typical HDR images would require many megabytes of storage but by applying BrightSide' JPEGHDR encoding, the size can be reduced to kilobytes. Compression of up to 25:1 can be achieved while maintaining excellent image quality and the final JPEGHDR image file is often only about 10% larger than a typical low dynamic range JPEG image.

For more demanding applications where lossless compression is required, compression rates of 3:1 to 8:1 can be achieved. In addition JPEGHDR compression is fully forward and backward compatible, allowing users the choice of working in low or high dynamic range.

Available as JPEGHDR for still images and MPEGHDR for video, BrightSide's image compression technology removes a major barrier to mainstream adoption of HDR image technology.

Abstract The transition from traditional 24-bit RGB to high dynamic range (HDR) images is hindered by excessively large file formats with no backwards compatibility. In this paper, we demonstrate a simple approach to HDR encoding that parallels the evolution of color television from its grayscale beginnings. A tone-mapped version of each HDR original is accompanied by restorative information carried in a subband of a standard output-referred image. This subband contains a compressed ratio image, which when multiplied by the tone-mapped foreground, recovers the HDR original. The tone-mapped image data is also compressed, and the composite is delivered in a standard JPEG wrapper. To na?ve software, the image looks like any other, and displays as a tone-mapped version of the original. To HDR-enabled software, the foreground image is merely a tone-mapping suggestion, as the original pixel data are available by decoding the information in the subband. Our method further extends the color range to encompass the visible gamut, enabling a new generation of display devices that are just beginning to enter the market.
