Syntax

public static void ColorDistance ( AvlNet.Pixel inPixelA, AvlNet.Pixel inPixelB, float inChromaAmount, out float outDistance )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inPixelA | AvlNet.Pixel | ||||
inPixelB | AvlNet.Pixel | ||||
inChromaAmount | float | <0.0f, 1.0f> | 0.7f | Proportion of chromatic information in distance computation. Default value: 0.7f. | |
outDistance | float |
Description
The operation computes the distance between two pixels.
The distance between pixels is computed using two measures:
- Value distance - the difference between average channel values
- Chromatic distance - euclidean distance between pixels normalized to the same value level
The resulting distance is computed as a weighted average of these two values, parameter inChromaAmount ( 0.0 - 1.0 ) being the weight of the chromatic distance, and 1 - inChromaAmount being the weight of the value distance.
