add mantiuk operator #4

Open billy2k19 opened 5 years ago

in addition to reinhard, hable, mobius - this mantiuk operator is one i might enjoy in the hdrtools.

it has a detail parameter that works quite well (on sdr content too) for enhancing highlights and shadows at the same time

anyway, here's an premade implementation (in c++) that uses the XYZ image format https://github.com/LuminanceHDR/LuminanceHDR/tree/master/src/TonemappingOperators/mantiuk06

edit bonus: here is a academic paper by mantiuk et al. on hdr tonemapping for video where he discusses combining methods like edge detection, noise reduction, and motion flow to get the best results https://www.cl.cam.ac.uk/~rkm38/pdfs/eilertsen2017tmo_star.pdf

Thanks for the information. I'll take a look, but if i add it, it will not soon unfortunately. After, i leave noise reduction to others plugin more efficient. Anyway, i'll take a look when i have time, but it will not be right now.
