Detailed Description

The method used is simple thresholding based on two thresholds : the lower and the upper thresholds. All voxels with values between the two thresholds (including the two thresholds themselves) are marked.

Thresholding can be controlled by using the following parameters:

• threshHigh : The higher threshold value
• threshLow : The lower threshold value

The output of the thresholding process can be configured using:

• insideVoxelMask : The mask to apply to the voxels which belong to the region
• insideVoxelMaskOp : The operation to be performed bet the mask and the actual voxel data

• outsideVoxelMask : The mask for voxels which do not belong to the region
• outsideVoxelMaskOp : Operation to be performed bet the mask and the voxel data

Member Function Documentation

void vlVolProcessorThresh::init (   )  [virtual]

If the volume argument is not valid, then init() is not called. Implement this function if you need to do any initialization before the user calls run. For e.g., this is the right place to add config parameters which are volume type dependent. Reimplemented from vlVolProcessor. Definition at line 61 of file thresholding.cpp. References vlVarListAdmin::add(), vlVarListAdmin::clear(), vlVolProcessor::configRef(), uint8, and vlVolProcessor::vol().

bool vlVolProcessorThresh::run (   )  [virtual]

Returns: true if successful, false otherwise. Implements vlVolProcessor. Definition at line 124 of file thresholding.cpp. References callFunctionOnDataTypeNoArgs, runT(), and vlVolProcessor::vol().

template<class DataType> bool vlVolProcessorThresh::runT (  DataType &  dummy  )  [protected]

Definition at line 138 of file thresholding.cpp. Referenced by run().

template<class DataType> bool vlVolProcessorThresh::thresholding (  DataType &  dummy  )  [protected]

This function expects the volume data to be a single value per voxel and with "<", ">" and "==" defined for the data type. Parameters: DataType  The data type of the volume data. dummy  A dummy variable just for templates Returns: true if thresholding was successful, false otherwise.
