Summary
Initializes a new KaufmannRegionCommand class object with explicit parameters.
Syntax
C#
C++/CLI
Python

Parameters

radius
Value that indicates the size of the neighborhood used for blurring each pixel of the image.

minimumInput
Value that specifies the image's shadows to be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images.

maximumInput
Value that specifies the image's highlights to be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images.

regionThreshold
Value that specifies the values that set the stopping point for the region.

regionStart
Value that indicates whether to remove all holes from the region that's created internally.

removeHoles
Value that indicates whether to remove all holes from the region that's created internally.

combineMode
Value that represent the action to take regarding the existing image region, if one is defined.
