How it works

  1. Convert the source video to 256x144 RGB frames
  2. Convert each pixel to HSL
  3. Spectrum X axis is pixel's Hue
  4. Color weight = Saturation * Median lightness difference
  5. Median lightness difference = chi square difference for the pixel's lightness and lightness range middle
