Dear all!
In my last post I have already hinted at new possibilities arising
from the use of OpenImageIO (OIIO for short). I found that it's quite
feasible to use OIIO's image importing code as a stand-in for vigra's
importImage. Now I've gone one step further and refitted some hugin
tools with OIIO code: pto_gen and cpfind. For pto_gen, I have just
changed the retrieval of image metrics to use OIIO, but in cpfind I
have also changed the image import code. With the modified tools, I
could run a tool chain from a set of RAW images to a readily-optimized
PTO file by using first the modified pto_gen, then the modified cpfind
and finally autooptimiser. The resulting PTO could be loaded into my
recent build of lux (the build from the oiio branch, for which I
offered an AppImage in my last post) which also employs OIIO and can
process RAW images as input. lux stitched this PTO into a seamless
panorama.
All of this was possible without any intermediate TIFF files on disk -
OIIO handles the loading and processing of RAW images in-library using
libRAW and presents the readily-converted data. I think with this
little experiment I have established that OIIO would make a good
candidate to replace vigra's ageing impex library - OIIO can also
handle newer formats like HEIF and webp, among many others. Since the
swapping-in of OIIO code for vigra code is quite painless, one might
assume that the entire hugin software collection could be refitted
like this, bringing hugin up-to-date with newer file formats and
adding RAW support.
And how does it handle the need for noise reduction and sharpening in
RAW files?
