Method Detail

• get_type

   String get_type()

• getBorderWidthFraction

   final Double getBorderWidthFraction()

  Ignore this fraction of pixels at the edge of the image when calculating statistics. Pixels at the edge of the image typically have poor statistics. Ignoring them and using only the inner pixels when calculating certain statistics can substantially improve the quality of the result. The value must be less than 0.5 but usually good values are between 0 and 0.15.

  Default is 0.06

• setBorderWidthFraction

   final Unit setBorderWidthFraction(Double borderWidthFraction)

  Ignore this fraction of pixels at the edge of the image when calculating statistics. Pixels at the edge of the image typically have poor statistics. Ignoring them and using only the inner pixels when calculating certain statistics can substantially improve the quality of the result. The value must be less than 0.5 but usually good values are between 0 and 0.15.

  Default is 0.06

• getBlackOutliersFraction

   final Double getBlackOutliersFraction()

  Clip this fraction of the darkest pixels in operations such as autocontrast. Increasing the range of middle gray levels at the expense of the brightest and darkest levels may improve the overall contrast and quality of the result. Sum of blackOutliersFraction and whiteOutliersFraction must be less than 1 but usually good values for the parameters do not exceed 0.05;

  Default is 0.0

• setBlackOutliersFraction

   final Unit setBlackOutliersFraction(Double blackOutliersFraction)

  Clip this fraction of the darkest pixels in operations such as autocontrast. Increasing the range of middle gray levels at the expense of the brightest and darkest levels may improve the overall contrast and quality of the result. Sum of blackOutliersFraction and whiteOutliersFraction must be less than 1 but usually good values for the parameters do not exceed 0.05;

  Default is 0.0

• getWhiteOutliersFraction

   final Double getWhiteOutliersFraction()

  Clip this fraction of the brightest pixels in operations such as autocontrast. Increasing the range of middle gray levels at the expense of the brightest and darkest levels may improve the overall contrast and quality of the result. Sum of blackOutliersFraction and whiteOutliersFraction must be less than 1 but usually good values for the parameters do not exceed 0.05;

  Default is 0.02

• setWhiteOutliersFraction

   final Unit setWhiteOutliersFraction(Double whiteOutliersFraction)

  Clip this fraction of the brightest pixels in operations such as autocontrast. Increasing the range of middle gray levels at the expense of the brightest and darkest levels may improve the overall contrast and quality of the result. Sum of blackOutliersFraction and whiteOutliersFraction must be less than 1 but usually good values for the parameters do not exceed 0.05;

  Default is 0.02

• toJson

   JSONObject toJson()

• default

   final static GrayscaleFilter default()
