Filter Image, Dual Output¶

../../../../_images/image_filtering_dual.svg

Filters one image using algorithms with two images as output

Documentation¶

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
