Detailed Description

Compute statistics for an image.

vtkImageHistogramStatistics computes statistics such as mean, median, and standard deviation. These statistics are computed from the histogram of the image, rather than from the image itself, because this is more efficient than computing the statistics while traversing the pixels. If the input image is of type float or double, then the precision of the Mean, Median, and StandardDeviation will depend on the number of histogram bins. By default, 65536 bins are used for float data, giving at least 16 bits of precision.

Set the percentiles to use for automatic view range computation. This allows one to compute a range that does not include outliers that are significantly darker or significantly brighter than the rest of the pixels in the image. The default is to use the first percentile and the 99th percentile.

Set lower and upper expansion factors to apply to the auto range that was computed from the AutoRangePercentiles. Any outliers that are within this expanded range will be included, even if they are beyond the percentile. This allows inclusion of values that are just slightly outside of the percentile, while rejecting values that are far beyond the percentile. The default is to expand the range by a factor of 0.1 at each end. The range will never be expanded beyond the Minimum or Maximum pixel values.
