READ THE DOCS

FILTERS

• AdaptiveBinarize: based on OpenCV's Adaptive Thresholding.
• Bilateral: A faster version of VapourSynth-Bilateral.
• BoxBlur: A faster version of std.BoxBlur.
• Checkmate: Spatial and temporal dot crawl reducer from AviSynth.
• CLAHE: Contrast Limited Adaptive Histogram Equalization from OpenCV.
• CombMaskMT: Port of MTCombMask from AviSynth.
• Metrics: Image metrics like SSIMULACRA2 and XPSNR.
• PlaneAverage: Vapoursynth PlaneStats with threshold.
• PlaneMinMax: Vapoursynth PlaneStats with threshold.
• RFS: Replace frames plugin.

BENCHMARK

src = core.std.BlankClip(None, 1920, 1080, vs.YUV420P16, 5000)

src.bilateral.Bilateral(ref=None, sigmaS=2, sigmaR=2, planes=[0,1,2]).set_output(1) 
# Output 5000 frames in 43.35 seconds (115.35 fps)
src.vszip.Bilateral(ref=None, sigmaS=2, sigmaR=2, planes=[0,1,2]).set_output(2) 
# Output 5000 frames in 35.37 seconds (141.36 fps)

src.std.BoxBlur(hradius=13, hpasses=1, vradius=13, vpasses=1).set_output(3) 
# Output 5000 frames in 16.74 seconds (298.60 fps)
src.vszip.BoxBlur(hradius=13, hpasses=1, vradius=13, vpasses=1).set_output(4) 
# Output 5000 frames in 4.78 seconds (1046.11 fps)

src.std.BoxBlur(hradius=13, hpasses=5, vradius=13, vpasses=5).set_output(5) 
# Output 5000 frames in 76.72 seconds (65.17 fps)
src.vszip.BoxBlur(hradius=13, hpasses=5, vradius=13, vpasses=5).set_output(6) 
# Output 5000 frames in 13.62 seconds (367.01 fps)
