Detailed Description

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

This filter implements the computation of the spectral angle distance with respect to a reference pixel.

Deprecated:

Spectral angle distance is an efficient way to convert spectral information to scalar data with respect to a reference pixel. The spectral angle distance is defined as:

\[SA = cos^{-1}\Big(\frac{{\sum_{b=1}^{n_{b}}}r(b)\cdot p(b)}{\sqrt{{\sum_{b=1}^{n_{b}}}r(b)^{2}{\sum_{b=1}^{n_{b}}p(b)^{2}}}}\Big) \]

with $b$ being the spectral band, $r$ the reference pixel and $p$ the current pixel.

Since the spectral angle deals with multi-bands image, the InputImage pixels are supposed to support the [] operator, and the input image to support the GetNumberOfComponentsPerPixel() method.

This filter is implemented as a multithreaded filter.

SpectralAngleDistanceImageFilter can be implemented as a multithreaded filter. Therefore, this implementation provides a ThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling ThreadedGenerateData(). ThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread"
