.. _`Filter Image, Dual Output`: .. _`syip.imagefiltering2`: Filter Image, Dual Output ~~~~~~~~~~~~~~~~~~~~~~~~~ .. image:: image_filtering_dual.svg :width: 48 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 :Inputs: **source** : image source image to filter :Outputs: **resultA** : image result after filtering **resultB** : image result after filtering *Ports*: **Inputs**: :source: image source image to filter **Outputs**: :resultA: image result after filtering :resultB: image result after filtering *Configuration*: **algorithm** (no description) **n** (no description) **sigma** (no description) **threshold** (no description) .. automodule:: node_filtering .. class:: ImageFiltering2
