Ideas for future improvements to the code (mostly a reminder to ourselves)

• [ ] Make solve2degree() a bit more robust by using a better 2nd-degree solver.
• [x] Renaming of, e.g., float2color3() → floatToColor3() etc, because in this case it is a bit confusing. When doing this, we should rename so no function uses a 2 instead of To
• [ ] Remove image() constructors that are not needed?
• [ ] Test if LDR images are in [0,1] and return warning or bool or something.
• [x] Overlapping histograms for C++ is missing.
• [ ] Fix constructor for FLIP::filename("tmp.png"); so that we do not need tmp but can set the extension (png).
• [ ] Rename saveHDROutputLDRImages() to something better, perhaps saveIntermediateLDRImages(). Same goes for corresponding variable names: returnLDRFLIPImages, hdrOutputFlipLDRImages, returnLDRImages, and hdrOutputLDRImages.
• [ ] Add more test/ref images + test of histograms.
• [ ] Handle the case when the median = 0
• [ ] Publish to PyPI
• [ ] Make it possible for Python version to run on GPU.
• [ ] Make a fast CUDA version of std::nth_element() (would make the HDR-version faster)
• [ ] Better handling of num channels and dimensions (if they differ). Do it in a single place for pyhton/cpp. If file does not exist, then we should never write any image.

Hi,

are there currently any efforts to publish flip to PyPI? Or is it really just a reminder? I think having flip on PyPi would be really useful to a lot of people.

Not at the moment, but we will get back to this topic! However, it will most likely be in the fall of 2024.
