ThresholderGlobal

public class ThresholderGlobal
extends Thresholder

Performs global thresholding.

This implies that the threshold-level is identical for every voxel.

The thresholding occurs inplace on the existing voxels i.e. a new buffer is not created.

An on voxel is placed in the buffer if voxel-value >= level or off otherwise.

Description copied from class: Thresholder

Thresholds voxels (across a range of values) so that they have only binary range (i.e. two voxel values representing on and off).

If a mask is used, the voxels outside the object-mask are left unchanged. They will be either identical to the input-volume or 0 if a new buffer needs to be created.

Specified by:

threshold in class Thresholder

Parameters:

inputBuffer - the voxels to be thresholded.

bvOut - what binary values to be used in the output.

histogram - a histogram if it's available, which must exactly match the intensity-values of voxels after any object-mask is applied. This exists for calculation efficiency.

objectMask - an object-mask to restrict thresholding to only some region(s) of the voxels.

Returns:

a binary-channel as described above, which may possibly reuse the input voxel-buffers.

Throws:

OperationFailedException - if the thresholding operation cannot complete successfully.
