Detailed Description

template<class TInputImage, class TOutputImage>
class otb::MultivariateAlterationDetectorImageFilter< TInputImage, TOutputImage >

This filter implements the Multivariate Alteration Detector.

This filter implements the Multivariate Alteration Detector, based on the following work:

A. A. Nielsen and K. Conradsen, "Multivariate alteration detection (mad) in multispectral, bi-temporal image data: a new approach to change detection studies," Remote Sens. Environ., vol. 64, pp. 1-19, (1998)

Multivariate Alteration Detector takes two images as inputs and produce a set of N change maps as a VectorImage (where N is the maximum of number of bands in first and second image) with the following properties:

Change maps are differences of a pair of linear combinations of bands from image 1 and bands from image 2 chosen to maximize the correlation.
Each change map is orthogonal to the others.

This is a statistical method which can handle different modalities and even different bands and number of bands between images.

If numbers of bands in image 1 and 2 are equal, then change maps are sorted by increasing correlation. If number of bands is different, the change maps are sorted by decreasing correlation.

The GetV1() and GetV2() methods allow retrieving the linear combinations used to generate the Mad change maps as a vnl_matrix of double, and the GetRho() method allows retrieving the correlation associated to each Mad change maps as a vnl_vector.

This filter has been implemented from the Matlab code kindly made available by the authors here: http://www2.imm.dtu.dk/~aa/software.html

Both cases (same and different number of bands) have been validated by comparing the output image to the output produced by the Matlab code, and the reference images for testing have been generated from the Matlab code using Octave.
