Sati

Statistical Analysis of Topographic Images

This package enables you to simultaneously

• subtract background (a polynomial surface, logarithmic decays, exponential decays)

• label terraces

• estimate terrace heights

• estimate the unit height of steps

even in the presence of steps.

Install

You can install the package from the git repogitory using pip

$ pip install sati

Requirements
