Method Details

threshold

public static ImageOp threshold(double... thresholds)

Apply a fixed threshold.

Parameters:

thresholds - either a single-element array (to set the same threshold everywhere), or an array with one element per channel.

Returns:

thresholdMeanStd

public static ImageOp thresholdMeanStd(double... k)

Threshold each channel based upon the channel mean and standard deviation. The threshold is mean + k * std.dev..

Parameters:

k -

Returns:

thresholdMedianAbsDev

public static ImageOp thresholdMedianAbsDev(double... k)

Threshold each channel based upon the channel median and median absolute deviation. The threshold is median + k * MAD / 0.6750., where the normalizing factor enables k to be comparable to a scale factor applied to a standard deviation (assuming a roughly normal distribution).

Parameters:

k -

Returns:
