  1. JPEG-HDR

    JPEG HDR is an extension to the standard JPEG File Interchange Format JPEG image file format allowing it to store high dynamic range imaging high dynamic range images . Overview JPEG HDR was created by Greg Ward and Maryann Simmons as a way to store High dynamic range imaging high dynamic range images inside a standard JPEG file. This reduces the file size required to store HDR images compared to other HDR formats such as floating point Tagged Image File Format TIFF and RGBE image format RGBE . It does this by first converting the image into a tone mapping tone mapped version and storing a reconstructive multiplier image in APP11 markers in the same JPEG file. Ordinary viewing software will ignore the multiplier image allowing anyone to see the tone mapped version of the image. Support Software programs that support JPEG HDR s include Photosphere by Greg Ward and pfstools. A Software Encoder was available from BrightSide Technologies formerly Sunnybrook Technologies, acquired by Dolby Laboratories in 2007 . Similar formats Other formats that use a similar idea of storing extra HDR information in a standard JPEG image include CLARITY HDR, XDepth both from Trellis Management and ERI from Kodak .

  1. Homology directed repair

    unreferenced date March 2008 Homology directed repair HDR is a mechanism in cell biology cells to repair double strand DNA lesions. This repair mechanism can only be used by the cell when there is a homologue piece of DNA present in the Cell nucleus nucleus , mostly in G2 and S phase of the cell cycle . When the homologue DNA piece is absent, another process called non homologous end joining NHEJ can take place instead. Cancer Suppression HDR is important for suppressing the formation of cancer . HDR maintains the genomic stability by repairing the broken DNA strand, assumed error free because of the use of a template. When a double strand DNA lesion is repaired by NHEJ there is no validating DNA template present which may result in a non original DNA strand formation with loss of information. A different nucleotide sequence in the DNA strand results in a different protein expressed in the cell. This protein may malfunction by which processes in the cell may fail. When, for example, a receptor of the cell that can receive a signal to stop dividing malfunctions, the cell ignores the signal and keeps dividing and can form a cancer. An example for the essence of HDR is the fact that the mechanism is conserved throughout evolution . The HDR mechanism has also been found in more simple organism s, like in yeast . Biological Pathway The pathway of HDR is not totally enlightened yet March 2008 . Though there are a lot of experimental results which point to the validity of certain models. Generally accepted is the phosphorylation of histone H2AX noted as H2AX within seconds after occurrence of the damage. H2AX is phosphorylated widely in the surrounding area of the damage and not only at the precise location. Therefore H2AX is suggested to function as an adhesive component to attract ... of Rad51 with the damage is accepted to be the definite point where HDR is initiated instead ... of HDR. br HDR and NHEJ repair double strand breaks.

It stores pixels as one byte each for RGB color model RGB red, green, and blue values with a one byte shared exponent. Thus it stores four bytes per pixel. RGBE s biggest advantage is that it allows pixels to have the extended range and precision of floating point values. Often when images are generated from light simulations, the range of pixels values is much greater than will nicely fit into the standard 0..255 range of standard 24 bit image formats. As a result the bright pixels are either clipped to 255 or end up losing all their precision in dimmer pixels. By using a shared exponent, the RGBE format gains some of the advantages of floating point values without the 12 bytes per pixel needed for single precision IEEE 754 1985 IEEE floating point values, or 6 bytes in half precision and which would cover smaller range . It can handle very bright pixels without loss of precision for darker ones. A second variant of the format uses the CIE 1931 color space XYZ color model with a shared exponent. The mime type and file extension is identical, thus applications reading this file format need to interpret the embedded information on the color model. Greg Ward provides code to handle RGBE files in his Radiance software Radiance rendering system.
