CoreImage: New Filters in iOS 14.0

iOS 14.0 recently arrived and with it, 3 new CoreImage filters:

  1. Color Absolute Difference
  2. Color Threshold
  3. Color Threshold Otsu

Unfortunately, Apple has not yet updated the CoreImage documentation to include these new filters. Instead, I’ve created a Swift playground that enumerates all of the properties of a CIFilter. Here are the results for those 3 filters:

[gist file=”ColorAbsoluteDifference.txt”]

[gist file=”ColorThreshold.txt”]

[gist file=”ColorThresholdOtsu.txt”]

I have no idea what the difference is between the Color Threshold and the Color Threshold Otsu filters. I’ll follow up if I can produce a workable demo.
