                 double z2,
                 int numberOfQuantizationSteps)

Method to perform trilinear interpolation along a line through an ImagePlus.

Parameters:

image - the ImagePlus

x1 - start x

x2 - end x

y1 - start y

y2 - end y

z1 - start z

z2 - end z

numberOfQuantizationSteps -

Returns:

the array with the interpolated values

evaluate

public java.lang.Object evaluate()

Specified by:

evaluate in class EvaluateROI

configure

public void configure()
               throws java.lang.Exception

Description copied from interface: GUIConfigurable

Configures the object before execution

Throws:

java.lang.Exception - may happen

toString

public java.lang.String toString()

Specified by:

toString in class EvaluateROI

trilinear

public double trilinear(ij.ImagePlus data3D,
               double x,
               double y,
               double z)

Trilinear Interpolation in an ImagePlus.
Adopted from Volume Viewer by Kai Uwe Barthel: barthel (at) fhtw-berlin.de This method is initialized in the first call with the volume dimensions to save computation time.
If this interpolation method is used from somewhere else, please use this method only on volumes of the same dimension. Instantiate one Measure3DBeadMTF Object per distinct volume dimension.

Parameters:

data3D - the ImagePlus

x - the x coordinate

y - the y coordinate

z - the z coordinate

Returns:

the interpolated value
