Field Detail

type

public ThresholdType type

Which algorithm to use

fixedThreshold

public double fixedThreshold

The threshold to apply to the image. Only valid for fixed threshold.

scale

public double scale

Scale factor applied to computed threshold. Only used with adaptive techniques. 0.95 is a good starting value when tuning. It will remove much of the noise in nearly uniform regions without degrading interesting features by much.

down

public boolean down

If true then it thresholds down

radius

public int radius

Radius of adaptive threshold.

savolaK

public float savolaK

Positive parameter used to tune threshold in Savola. Try 0.3

ThresholdType.LOCAL_SAVOLA

minPixelValue

public int minPixelValue

Minimum pixel value. Only used for some algorithms.

maxPixelValue

public int maxPixelValue

Maximum pixel value. Only used for some algorithms.

Method Detail

fixed

public static ConfigThreshold fixed(double value)

global

public static ConfigThreshold global(ThresholdType type)

local

public static ConfigThreshold local(ThresholdType type,
                                    int radius)

checkValidity

public void checkValidity()

Description copied from interface: Configuration

Checks to see if the configuration is valid. If it is invalid, throw an exception explaining what is incorrect.

Specified by:

checkValidity in interface Configuration

toString

public java.lang.String toString()

Overrides:
