Detailed Description

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

This filter performs the computation of the Harris measure as followed.

The derivative computation is performed by a convolution with the derivative of a Gaussian kernel of variance $\sigma_D$ (derivation scale) and the smoothing of the image is performed by convolving with a Gaussian kernel of variance $\sigma_I$ (integration scale). This allows the computation of the following matrix:

\[ \mu(\mathbf{x},\sigma_I,\sigma_D) = \sigma_D^2 g(\sigma_I)\star \left[\begin{array}{cc} L_x^2(\mathbf{x},\sigma_D) & L_xL_y^2(\mathbf{x},\sigma_D)\\ L_xL_y^2(\mathbf{x},\sigma_D)& L_y^2(\mathbf{x},\sigma_D) \end{array}\right] \]

The output of the detector is $[det(\mu) - \alpha trace^2(\mu)$.

The interest points can then be extracted with a thresholding filter.
