Filters one image using algorithms with two images as output

Documentation

Filters one image using algorithms with two images as output

Algorithms:

  • corner_foerstner

    Computes Foerstner corner measure response images. Outputs error eclipse sizes (top) and roundness or error eclipse (bottom).

    sigma:

    Standard deviation of gaussian kernel (default 1.0)

  • hessian eigenvalues

    Computes the eigenvalues of the hessian matrix for each pixel. Returns larger eigenvalue in first output image and smaller in second

    sigma:

    Standard deviation of gaussian kernel (default 3.0) used for calculating Hessian.

    Approximation is not reliable for sigma < 3.0
