| imganiso2D {adimpro} | R Documentation |
The function creates an object of class adimpro that
visualizes anisotropy information using the HSI color space for
main direction of anisotropy (H), maximum eigenvalue^satexp (S)
and log(excentricity) (I).
imganiso2D(x, satexp = 0.25, g=3, rho=0)
x |
a field of 2D tensors (Dimension c(3,n1,n2)) or an object of class "adimpro". |
satexp |
exponent for maximum eigenvalue in saturation channel. Determines the contrast in this channel. |
g |
Bandwidth for anisotropic smoothing gradient estimates, preferably g >= 3 for images with line type texture and small g approx 1 for improving edges between homogeneous regions. |
rho |
Regularization parameter for anisotropic smoothing gradient estimates, preferably rho = 0 for images with line type texture and large rho approx 3*variance for improving edges between homogeneous regions. |
an object (image) of class adimpro.
