Hi, In the meantime, I've become more familiar with the topic and I have further questions. As reported I still do not have a color chart. Currently I would be interested in the board of CMP or Wolf Faust but both have a point that prevents me from buying. 1.) CMP offers the Digital Target 8

[darktable-dev] An algorithm to downscale raw data BEFORE demosaic by whatever scale factor

2018-09-05 Thread rawfiner
Hi! Some of you may now that I am working on a raw denoising algorithm. One of the hard thing was that prior to demosaic, the algorithms are computed on unscaled data, while after demosaic the algorithms can compute a preview on a downscaled image, which is easier in terms of speed. So I tried to

OK, I'll bite. What's a GMIC filter when it's at home? :) Cheers, Bruce Williams -- audio2u.com brucewilliamsphotography.com shuttersincpodcast.com sinelanguagepodcast.com e-mail | Twitter | LinkedIn

hi heiko! this sounds great! as to your question, integrate gmic or reimplement. does it make much of a difference? can the code run on cropped regions of interest and in floating point? does it work for preview, i.e. does a downscaled image look similar when processed to first processing and
