Feb 22, 2012 at 16:55 | comment | added | Mr. White | the huffyuv mentioned below is quite similar to your own 'delta+arithmetic' suggestion. Although obviously it uses huffman instead of arithmetic coding for the entropy coding part. on 8 bits/pixel it typically reaches slightly above 2x compression, with only 1 line-buffer. | |

Feb 1, 2012 at 13:02 | comment | added | Martin Thompson | @JasonR: Thanks for the comments - they match my initial perceptions also - I'm in a weirdly constrained place, so I'll have to make my own weirdly constrained techniques up :) | |
Feb 1, 2012 at 5:22 | comment | added | Jason R | @MartinThompson: I doubt you'll find many compression formats targeted to your constraints. Processing power and memory are so plentiful nowadays, there's little motivation for developing algorithms with such low overhead. I think you'd need to roll something of your own. The lossless nature of what you need also points toward a general data compression algorithm (instead of being image-specific); you might have some success looking on Stack Overflow or elsewhere for help. | |

Jan 27, 2012 at 16:18 | comment | added | Martin Thompson | @JasonR: I have done a bit of investigation on "standard" techniques, but my (possibly innaccurate?) impression is they seem to be too dynamic and fairly memory hungry (relative to my "even 1K stretches it" criterion :) | |
Jan 27, 2012 at 16:14 | comment | added | Martin Thompson | @PaulR - question updated - the pixels will be padded. | |

Added description of pixel packing

Jan 27, 2012 at 16:04 | comment | added | Jason R | Seems like there aren't many image-specific requirements there. At the risk of sounding obvious, have you considered trying a standard streaming-data compression algorithm, like zlib, LZMA, etc.? | |
Jan 27, 2012 at 15:42 | comment | added | Paul R | Are your 10 - 16 bit pixels always padded to say, 16 bits, or are they packed ? | |
