Detailed Description

The purpose of this class is to take in an XML element that defines a set of ROI's, a set of images, filters to apply to the ROI's/images, and a set of statistics to be computed. Then statistics for every combination will be computed using svkImageStatistics and an XML data element will be output containing the results of the computation.

TODO: Should this be converted into an svkImageAlgorithmWithPortMapper?

double ComputeModeFromHistogram ( vtkDataArray *  histogram, double  binSize, double  startBin, int  smoothBins  )

static

Referenced by svkImageStatistics::ComputeSmoothStatistics(), and svkImageThreshold::RequestData().

vector< double > ComputeQuantilesFromHistogram ( int  numQuantiles, vtkDataArray *  histogram, double  binSize, double  startBin, int  numBins, int  smoothBins  )

Referenced by svkImageStatistics::ComputeSmoothStatistics(), and svkImageMathematics::Update().

double GetAutoAdjustedBinSize ( svkMriImageData *  image, double  startBinSize, double  startBin, int  numBins  )

static

This method is to support a legacy feature to automatically adjust the binsize.

Referenced by svkImageThreshold::RequestData(), and svkImageStatistics::RequestData().

vtkFloatArray * GetHistogram ( vtkDataArray *  data, double  binSize, double  startBin, int  numBins, int  smoothBins = 0  )

static

Generates a histogram for the given vtkDataArray. If smoothBins is greater then one then the histogram is smoothed. If smoothBins is even then the next highest odd number is used.

Referenced by svkImageStatistics::ComputeSmoothStatistics(), svkImageThreshold::RequestData(), and svkImageMathematics::Update().

vtkDataArray * GetMaskedPixels ( svkMriImageData *  image, svkMriImageData *  roi, double  minIncluded = 1, double  maxIncluded = VTK_DOUBLE_MAX  )

static

This method takes every pixel within the input image data that correspond to values > 0 in the roi image. Only looks at the current scalars. Only values >= minIncluded and <= maxIncluded are included.
