bayer转RGB的C源码

Just becuase there are some recent commits does not mean this is a > maintained project :) -- Jeff circa 2021 bayer2rgb will convert naked (no header) bayer grid data into rgb data. There are several choices of interpolation . It can output tiff files, and can integrate with ImageMagick to output other formats. The `bayer.c` was borrowed from the libdc1394 project [1], it is licensed under LGPL. The interpolation algorithms used are described at [3]. This is an implementation of the idea I stumbled upon on ImageMagick's mailing list while searching for a bayer grid converter. The thread can be found at [2]. ## Building ```bash mkdir build/ && cd build/ cmake .. -DCMAKE_BUILD_TYPE=Release cmake --build . --config Release ctest --verbose ``` ### Installing ```bash cp delegates.xml ~/.config/ImageMagick/ ``` ## Running usage: ./bayer2rgb --input,-i input file --output,-o output file --width,-w image width (pixels) --height,-v image height (pixels) --bpp,-b bits per pixel --first,-f first pixel color: RGGB, GBRG, GRBG, BGGR --method,-m interpolation method: NEAREST, SIMPLE, BILINEAR, HQLINEAR, DOWNSAMPLE, EDGESENSE, VNG, AHD --tiff,-t add a tiff header --swap,-s if bpp == 16, swap byte order before conversion --help,-h this helpful message ## Links 1. https://damien.douxchamps.net/ieee1394/libdc1394/ 2. http://www.imagemagick.org/pipermail/magick-developers/2008-May/002953.html 3.
