Deoldify Vapoursynth filter

[Dan64]

Hello Selur,

   I was finally able to apply in HAVC some of color adjustment filters that I developed in Vapoursynth described is this post: New AutoColor adjustment filter

   The results are satisfactory as you can see in the picture below

      

   With the previous version (image on the left) the colors were dull with a majority of "rose" color (the color of skin), with the new version (image on the right) both problems has been solved.

   To reduce the impact on GUI I recycled the parameter BlackWhiteTune, which now can have the following values:

:param BlackWhiteTune:      This parameter allows to improve contrast and luminosity of frames colored with HAVC.
                            Allowed values are:
                                    'None' (default)
                                    'Light',
                                    'Medium',
                                    'Strong'
                                    'Light+Custom',
                                    'Medium+Custom',
                                    'Strong+Custom'
                                    'Light+Restore',
                                    'Medium+Restore',
                                    'Strong+Restore'

 
  In the GUI is also necessary to add the following new parameter (a numeric combo-box):

:param BlackWhiteMode:      Method used by BlackWhiteTune to perform colors adjustments.
                             Allowed values are:
                                      0 : Apply Contrast Limited Adaptive Histogram Equalization on Luma
                                      1 : Apply simple Histogram Equalization on all RGB channels
                                      2 : Apply CLAHE on all RGB channels
                                      3 : method=0 and method=1 are merged
                                      4 : Automatic brightness and contrast optimization with ScaleAbs
                                      5 : Auto brigh and contrast optim. with saturation arithmetic (default)

 
I attached the RC1 of new version 5.5.0 and a sample containing the new colorization cases introduced by the new/changed parameters

I hope that you had time to updated the filter and the GUI.

Thanks,
Dan
