Detailed Description
compute the outliers in a set of 2D histograms and extract the corresponding row data.
This class takes a table and one or more vtkImageData histograms as input and computes the outliers in that data. In general it does so by identifying histogram bins that are removed by a median (salt and pepper) filter and below a threshold. This threshold is automatically identified to retrieve a number of outliers close to a user-determined value. This value is set by calling SetPreferredNumberOfOutliers(int).
The image data input can come either as a multiple vtkImageData via the repeatable INPUT_HISTOGRAM_IMAGE_DATA port, or as a single vtkMultiBlockDataSet containing vtkImageData objects as blocks. One or the other must be set, not both (or neither).
The output can be retrieved as a set of row ids in a vtkSelection or as a vtkTable containing the actual outlier row data.
