Detailed Description

template<class TImageType, class THistogramFrequencyContainer = DenseFrequencyContainer>
class itk::Statistics::ScalarImageToGreyLevelCooccurrenceMatrixGenerator< TImageType, THistogramFrequencyContainer >

This class computes a grey-level co-occurence matrix (histogram) from a given image. GLCM's are used for image texture description.

This generator creates a grey-level co-occurence matrix from a N-D scalar image. This is the first step in texture description a la Haralick. (See Haralick, R.M., K. Shanmugam and I. Dinstein. 1973. Textural Features for Image Classification. IEEE Transactions on Systems, Man and Cybernetics. SMC-3(6):610-620. See also Haralick, R.M. 1979. Statistical and Structural Approaches to Texture. Proceedings of the IEEE, 67:786-804.)

The basic idea is as follows: Given an image and an offset (e.g. (1, -1) for a 2-d image), grey-level co-occurences are pairs of intensity values for a specific pixel and the pixel at that offset from the specified pixel. These co-occurences can provide information about the visual texture of an image region -- for example, an eight-bit image of alternating pixel-wide white and black vertical lines would have a large number of (0, 255) and (255, 0) co-occurences for offset (1, 0).

The offset (or offsets) along which the co-occurences are calculated can be set by the user. Traditionally, only one offset is used per histogram, and offset components in the range [-1, 1] are used. For rotation-invariant features, averages of features computed over several histograms with different offsets are generally used, instead of computing features from one histogram created with several offsets. Additionally, instead of using offsets of two or more pixels in any direction, multy-resulution techniques (e.g. image pyramids) are generally used to deal with texture at different spatial resolutions.

This class calculates a 2-d histogram of all the co-occurence pairs in the given image's requested region, for a given set of offsets. That is, if a given offset falls outside of the requested region at a particular point, that co-occurrence pair will not be added to the matrix.

The number of histogram bins on each axis can be set (defaults to 256). Also, by default the histogram min and max corresponds to the largest and smallest possible pixel value of that pixel type. To customize the histogram bounds for a given image, the max and min pixel values that will be placed in the histogram can be set manually. NB: The min and max are INCLUSIVE.

Further, the type of histogram frequency container used is an optional template parameter. By default, a dense container is used, but for images with little texture or in cases where the user wants more histogram bins, a sparse container can be used for the histogram instead.

WARNING: This probably won't work for pixels of double or long-double type unless you set the histogram min and max manually. This is because the largest histogram bin by default has max value of the largest possible pixel value plus 1. For double and long-double types, whose "RealType" as defined by the NumericTraits class is the same, and thus cannot hold any larger values, this would cause a float overflow.
