Color to Grayscale
Color to grayscale conversion, uses envelopes formed with the STRESS approach to perform local color-difference preserving grayscale generation.
Neighborhood taken into account, this is the radius in pixels taken into account when deciding which colors map to which gray values
name: radius type: int default: 300 minimum: 2 maximum: 6000 ui-minimum: 2 ui-maximum: 1000 ui-gamma: 1.60 ui-step-small: 1 ui-step-big: 100 unit:pixel-distance
Number of samples to do per iteration looking for the range of colors
name: samples type: int default: 4 minimum: 1 maximum: 1000 ui-minimum: 3 ui-maximum: 17 ui-gamma: 1.00 ui-step-small: 1 ui-step-big: 5
Number of iterations, a higher number of iterations provides less noisy results at a computational cost
name: iterations type: int default: 10 minimum: 1 maximum: 1000 ui-minimum: 1 ui-maximum: 30 ui-gamma: 1.00 ui-step-small: 1 ui-step-big: 5
