HistBinNum

Defines the size of one dimension of a three-dimensional RGB histogram that is used internally by the algorithm. It often makes sense to increase the number of bins for images with higher bit depth (e.g. 256 bins for a 12 bit image).

Declaration
public int HistBinNum { get; set; }
Property Value
Type Description
System.Int32

RangeMaxVal

Maximum possible value of the input image (e.g. 255 for 8 bit images, 4095 for 12 bit images)

Declaration
public int RangeMaxVal { get; set; }
Property Value
Type Description
System.Int32

SaturationThreshold

Threshold that is used to determine saturated pixels, i.e. pixels where at least one of the channels exceeds

Declaration
public float SaturationThreshold { get; set; }
Property Value
Type Description
System.Single
