Introduction:
JPEG XR (formerly Windows Media Photo and HD Photo) is a still-image compression standard and file format for continuous tone photographic images, based on technology originally developed and patented by Microsoft as a part of the Windows Media family. It supports both lossy and lossless compression. This standard is as per ISO/IEC 29199-2, ITU-T T.832 specification.
Features:
• IPP JPEG-XR sample codec supports
• 8u, 16s, 16u, 32s, 16f, 32f images encode and decode
• RGB/BGR/CMYK with and without alpha channel, Gray images
• Internal YUV444 sampling
• Tiling encode and decode
• 50+ new IPP functions for JPEG-XR, including:
• Forward and Inverse Core transforms
• Variable Length Code (VLC) functions
• UIC JPEGXR is threaded on codec level
Advantages compare to JPEG :
JPEG XR offers some dramatic benefits when compared to the original JPEG file format, key benefits are,
√ Higher compression(100:1 vs. 10:1)√ Broader data ranges -More image formats (8-16-32 bpp vs. 8-12 bpp)(bpp- bit-per-pixel)
√ Advanced decoding features
√ Richer color support
