tend sten [-ds <diff. scale>] [-is <int. scale>] [-df <downsample factor>] [-i <nin>] [-o <nout>]

Calculate structure tensors from a scalar field. Not a diffusion tensor, but it is symmetric and positive-definite.

-ds <diff. scale>

differentiation scale, in pixels: the radius of the kernel used for differentation to compute gradient vectors (int); default: “1”

-is <int. scale>

integration scale, in pixels: the radius of the kernel used for blurring outer products of gradients in order compute structure tensors (int); default: “2”

-df <downsample factor>

the factor by which to downsample when creating volume of structure tensors (int); default: “1”

-i <nin>

input scalar volume; default: “-”

-o <nout>

output filename (string) default: “-”
