Interface	Description
Distance	An abstract definition of a distance measure between two coordinates or image points.
GradientSource	Defines a class from which image gradients can be obtained.

Class Summary

Class	Description
DerivativeImage	Calculates the standard derivatives Dx and Dy of an image using a -1,0,1 kernel and stores the results in separate ImageProcessors.
DistanceL2	Euclidean distance (L2) d = Math.sqrt(x^2 + y^2)
Extractor	Class used as a commandline tool to extract features from directories of images.
GeometricBlur	Gaussian Blur where sigma is modified according to spacial position to the "query point".
GradientImage	Class that calculates gradients from a given image.
Histogram	A histogram class for counting occurences of values.
IntegralImage	Integral images are an efficient way to retrieve the sum of pixel intensities in any rectangular region of the image.
Interpolated1DHistogram	The Interpolated1DHistogram class is used to create interpolates histograms for a certain range of values ([min,max[) with a defined range of bins.
PackageScanner<T>	The PackageScanner class is used to find classes deriving a certain class within a package.
