class itk::AdaptiveHistogramEqualizationImageFilter< TImageType, TKernel >
Power Law Adaptive Histogram Equalization.
Histogram equalization modifies the contrast in an image. The AdaptiveHistogramEqualizationImageFilter is a superset of many contrast enhancing filters. By modifying its parameters (alpha, beta, and window), the AdaptiveHistogramEqualizationImageFilter can produce an adaptively equalized histogram or a version of unsharp mask (local mean subtraction). Instead of applying a strict histogram equalization in a window about a pixel, this filter prescribes a mapping function (power law) controlled by the parameters alpha and beta.
The parameter alpha controls how much the filter acts like the classical histogram equalization method (alpha=0) to how much the filter acts like an unsharp mask (alpha=1).
The parameter beta controls how much the filter acts like an unsharp mask (beta=0) to much the filter acts like pass through (beta=1, with alpha=1).
The parameter window controls the size of the region over which local statistics are calculated.
By altering alpha, beta and window, a host of equalization and unsharp masking filters is available.
The boundary condition ignores the part of the neighborhood outside the image, and over-weights the valid part of the neighborhood.
