Constructor Detail

Filter

public Filter(float sigmaR,
              float sigmaX,
              float sigmaY,
              float sigmaZ)

Constructor.

Method Detail

setLog

public void setLog(boolean log)

Specifies the log status.

setMultithread

public void setMultithread(boolean multithread)

Specifies the multithread status.

setIterativeScheme

public void setIterativeScheme(int nbIteration,
                               int modeIteration)

Specifies the iterative scheme.

selectChannels

public void selectChannels(int methodSelectionChannels,
                           double valueSelectionChannels)

Specifies the select of the channels.

computeOrder

public int[] computeOrder(Data data)

Determines the order of the filter. The order is function of the input dynamic range (T) and the size of the filter in the range domain (sigmaR). To avoid too many channels only a subset of the channels can be optionally applied. This selection of the channel is based on the user choice: 1) Best: only the channels corresponding to a weight which is 0.001 larger than the larger one is take in account 2) All: all channels 3) By truncate: 4) By tolerance:

execute

public float[] execute(additionaluserinterface.WalkBar walk,
                       Data data,
                       int channel)

Processes the image (in).

approximate

public float[] approximate(Data data,
                           float[] gaussian,
                           float[] approx)

Return 3 indicators of the quality of the approximation of the gaussian function discretized over number of bins elements. 1. RMSE (0 is perfect) 2. Undershoot: most negative value (0 is perfect) 3. Lost of gain: 1 - approx(0) (0 is perfect)
