Is there a relatively easy to use tool that will allow me to demosaic some raw data stored in a TIFF file (not a standard raw file such as DNG, NEF, etc.), assuming a Bayer pattern? The TIFF contains no metadata, so should be possible to specify any necessary additional information separately.

Use case: same as here. –  Szabolcs Sep 13 '13 at 15:36
    
Do you have three different color layers and are trying to demosaic and combine, or an already combined file with some patterns you are trying to remove? –  Patrick Hurley Sep 13 '13 at 15:50
    
@PatrickHurley I have a single channel which looks like no. 2 here. I'm looking for a tool that'll reconstruct no. 4. I'm not looking to implement it myself. –  Szabolcs Sep 13 '13 at 18:17

This question appears to be off-topic because it is about programming for image processing, not about photography. –  mattdm Dec 22 '13 at 13:58
    
@mattdm It's not about programming, nor about image processing methods. The question is asking for a software tool to do something, like many other questions on this site. –  Szabolcs Dec 22 '13 at 15:55

Most raw formats are actually stored in .tiff containers. They're simply proprietary data in a .tiff container.

Three thoughts for you for what you are trying to do:

1) Try Dave Coffin's DCRaw package, without or with a GUI front-end.

2) You could also read the file into Photoshop as a (.raw) format; it would come in as a single plane and require manipulation to be converted to RGB.

3) If you are or know a programmer, it would not be hard to parse this from a simple TIFF file without any metadata (perhaps an hour's work or so).
