Usage

1
2
diffusion_tensors(im, sharpness = 0.7, anisotropy = 0.6, alpha = 0.6,
  sigma = 1.1, is_sqrt = FALSE)

Arguments

im

an image

sharpness

Sharpness

anisotropy

Anisotropy

alpha

Standard deviation of the gradient blur.

sigma

Standard deviation of the structure tensor blur.

is_sqrt

Tells if the square root of the tensor field is computed instead.
