An abstract definition of a distance measure between two coordinates or image points.
Defines a class from which image gradients can be obtained.
Calculates the standard derivatives Dx and Dy of an image using a -1,0,1 kernel and stores the results in separate ImageProcessors.
Euclidean distance (L2)
Class used as a commandline tool to extract features from directories of images.
Gaussian Blur where sigma is modified according to spacial position to the "query point".
Class that calculates gradients from a given image.
A histogram class for counting occurences of values.
Integral images are an efficient way to retrieve the sum of pixel intensities in any rectangular region of the image.
The PackageScanner class is used to find classes deriving a certain class within a package.
