what raw formats are supported #10

Hi Michael,

I'm testing the demosaicnet on Sony raw file (.ARW). I used Libraw to generate .tiff bayer pattern, with the same command in your README: dcraw -T -d -W -6 {filename}

Then feed the .tiff file into the network. The output always looks greenish, seems to have a really bad white balance. I used Libraw to process that raw file: dcraw -T -o 0 -M -W -6 {filename}, and am able to get reasonable output.

Is it required to do pre-white balance to the bayer pattern?

Also, in your provided raw file, is that in linear color space?

Thanks for helping

Hi,

Yes the file should be linear provided you pass the right flag to libraw (-g 0 0 i believe). The network assumes the mosaic is already white balanced.

Best,

Mika
