Deoldify Vapoursynth filter

[Dan64]

I just released the version: v4.5.1

I Improved Scene detection algorithm (implemented in the class SceneDetection).

In HAVC_main() have been added the following parameters:

• ScThtOffset: Offset index used for the Scene change detection. The comparison will be performed, between frame[n] and frame[n-offset]. An offset > 1 is useful to detect blended scene change, range[1, 25]. Default = 1.
  
• ScMinInt: Minimum number of frame interval between scene changes, range[1, 25]. Default = 1.
  

In HAVC_ddeoldify() have been added the following parameters:

• sc_tht_offset: Offset index used for the Scene change detection. The comparison will be performed, between frame[n] and frame[n-offset]. An offset > 1 is useful to detect blended scene change, range[1, 25]. Default = 1.
  
• sc_min_int: Minimum number of frame interval between scene changes, range[1, 25]. Default = 1.
  

In the class SceneDetection I reimplemented the Vapoursynth function misc.SCDetect using the Vapoursynth function std.PlaneStats.

The new implementation is activated if the following conditions are verified: sc_tht_filter > 0.0 or threshold < 0.05 or tht_offset > 1.

The suggested parameters for scene detection are:

• ScThreshold=0.10 
  
• ScThtOffset=10 
  
• ScMinFreq=15
  
• ScMinInt=5 
  
• ScThtSSIM=0.65
  
• ScNormalize=True
