ThresholdToRegion_Color

Creates a region containing image pixels with values close to the given color.

Name	Type	Range	Description
inImage	Image		Input image
inRoi	Region *		Region of interest
inRgbColor	Pixel		Color to compare the image to
inChromaAmount	Real	0.0 - 1.0	Proportion of chromatic information in distance computation
inMaxDifference	Real	0.0 -	Maximum difference between image pixel and model color
inHysteresis	Real	0.0 -	Defines how much the difference criterium is lowered for pixels neighboring with other foreground pixels
outRegion	Region		Output region

Only the following inImage pixel formats are supported: 1xuint8, 2xuint8, 3xuint8, 4xuint8

Color analysis with a given reference color.

Define the reference color by setting the inRgbColor input. You can use the Color Picker tool on an image preview and then copy-and-paste the value.
Increase inChromaAmount to make the filter less sensitive to changes in brightness. Decrease it to make brightness more important.
Set inMaxDifference experimentally to a value that best separates the foreground and background pixels.

Description of usage of this filter can be found in examples and tutorial: Rubber Ring.

ThresholdToRegion_Color performed on a sample image with inRgbColor = (192, 34, 22), inChromaAmount = 1.0, inMaxDifference = 48.

This operation is optimized for SSE2 technology for pixels of types: 1xUINT8, 3xUINT8.

This operation supports automatic parallelization for multicore and multiprocessor systems.

This filter is available on Basic Complexity Level.

This filters is member of ThresholdToRegion filter group.
