Deoldify Vapoursynth filter

[Dan64]

Hello Selur,

  I released the new RC3 (attached) and I hope that it will be the final one.

 The main changes are:

1) in HAVC_deepex() the parameter "enable_resize" has been replaced by the parameter "ref_merge"
    With the following description:
    

Method used by DeepEx to merge the reference frames with the frames propagated by DeepEx.
 It is applicable only with DeepEx method: 0, 1, 2.
 The HAVC reference frames must be produced with frequency = 1.
 Allowed values are:
        0 = No RF merge (reference frames can be produced with any frequency)
        1 = RF-Merge Low (reference frames are merged with low weight)
        2 = RF-Merge Med. (reference frames are merged with medium weight)
        3 = RF-Merge High (reference frames are merged with high weight)

  
  the tricky part is that this method (when > 0) requires that in the function HAVC_ddeoldify the parameter "sc_min_freq" is set = 1.
  Since this parameter is included in a separate function I cannot enforce it, in this case should be Hybrid to set sc_min_freq=1 when  ref_merge  > 0.

2) in HAVC_main I added the parameter DeepExRefMerge to manage the value of parameter "ref_merge" in HAVC_deepex() (it is just a propagation)

    This method has been added to fix the problem reported in post: #500

    The results are quite satisfatory, here the frame 20 colored using DeepEx



   the image was obtained using the following code:

clip = HAVC_main(clip, Preset='Fast', ColorFix='Violet/Red', ColorTune='Light', EnableDeepEx=True, DeepExMethod=1, DeepExPreset='Medium', DeepExRefMerge=2, ScFrameDir="D:/Tests/Green/ref_color")

   
 and the following reference image



 I hope you have time to adapt the GUI.

Thanks,
Dan
