Transforms each pixel value to minimum or maximum depending on whether it belongs to the specified range for each individual pixel component.
Namespace: | AvlNet |

Assembly: | AVL.NET.dll |
Syntax
public static void ThresholdImage_RGB ( AvlNet.Image inRgbImage, float inFuzziness, AvlNet.Image outMonoImage )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inRgbImage | AvlNet.Image | Input image, usually in the RGB color space. | |||
inFuzziness | float | <0.0f, INF> | Tolerance for the ranges that results in intermediate output values. | ||
outMonoImage | AvlNet.Image |
Description
The operation transforms each pixel of three-channel inRgbImage to the maximum or minimum level thus creating binary image. The input image is considered to be encoded using RGB color representation.
- Pixels meeting all of the following conditions are transformed to the maximum level:
- Intensity of the "red" channel is in range (inMinRed, inMaxRed).
- Intensity of the "green" channel is in range (inMinGreen, inMaxGreen).
- Intensity of the "blue" channel is in range (inMinBlue, inMaxBlue).
- Other pixels are transformed to the maximum level.
If any of the parameters inMinRed, inMinGreen, inMinBlue is not set, it is assumed to be -infinity. If any of the parameters inMaxRed, inMaxGreen, inMaxBlue is not set, it is assumed to be infinity.
Parameter inFuzziness (set to 0 by default) allows to perform fuzzy thresholding which linearly interpolates those pixel values that differ by at most inFuzziness from the border channel intensities; thus creating smooth transition between minimum and maximum values in the resulting image.
Examples
Hardware Acceleration
This operation supports automatic parallelization for multicore and multiprocessor systems.
Hardware acceleration settings may be manipulated with Settings class.
