Prefiltering

  • These prefiltering thresholds can be edited by Ultimate users. An image will be prefiltered out if any of these thresholds are reached or exceeded.

  • Entropy Threshold: The randomness of an image’s pixels. Lower means less random, higher means more random.

  • Edge Density Threshold: Used to distinguish how detailed an image is. Lower means smoother with few transitions, higher means more complex with more transitions.
