Interesting project. Saw you are hosting it on SourceForge but can't find your source code. I haven't tried it out yet because I'm deep into helping out on another project, folder_ProRes444_lut which is a part of
cr2hdr-r OSX batch conversion app (dng, CR2 ,MLV, RAW, HDR video) -- yeah I know it is confusing and it is OS-X only.
In any case, I just thought I'd share some "focus pixel" fixing we've been experimenting with and perhaps you could share your methods. Basically there are a couple of methods. One is using pixel mapping like with the
PinkDotRemover tool - this is effective but that tool hasn't been maintained for a while and has never worked properly for me. The other method is doing a chroma smoothing that processes the entire image and takes longer to run. Sometimes these methods aren't 100% effective and they don't work on dual_iso, at least not yet. That's what I'm working on.
Currently I'm experimenting with running a "bad pixel" file in dcraw and have gotten some fairly good results. Here's a topic that I started on
dealing with focus pixels. I put a focus pixel map file in my
bitbucket download area and will try to update it with other cameras, resolutions, crop mode and non-crop mode, etc. when I can get around to it. In the meantime. Please feel free to comment, PM me, scream at me or whatever it takes if you can figure out how to get rid of focus pixels on dual iso.
One more thing, "cr2hdr --really-bad-pix" does get rid of the focus pixels but it pretty much destroys the images that I have ran it on.
