f90fd5b0da Split CLAHE into its own file, because it's faster that way.
Yes, it's as ludicrous as it sounds, but it's still true. Bizarrely,
the previous commit makes CLAHE run about 10% slower on Android, even
though it doesn't even touch any CLAHE code. Splitting it off fixes that,
although the reason it does is a mystery for the ages.

It's cleaner when it's in its own file, anyway. ;=]

29b13ec1de Replaced most of the usages of parallel_for with that of parallel_for_.
This should allow many algorithms to take advantage of more parallelization
technologies.

0bbba847a4 Fix equalization formula in equalizeHist function & rewrite in C++
Old implementation did

    lut[i] = 255 * (count(Y <= i)) / (width * height)

which actually shifts uniform histograms.
From now histogram is equalized as

    C = count(Y == min(Y))
    lut[i] = 255 * (count(Y <= i) - C) / (width * height - C)
