sfd: Calculate the fractal dimension of a raster.

Description

Calculates the 3D fractal dimension of a raster using the triangular prism surface area method.

Usage

sfd(x, silent = FALSE)

Value

A numeric value representing the fractal dimension of the image.

Arguments

x

A raster or matrix.

silent

Logical. If FALSE (default), the function will print warning messages.
