We present an open source software implementation of a popular mathematical method developed by M.R.Yeadon for calculating the body and segment inertia parameters of a human Masalas body.The software is written in a high level open source language and provides three interfaces for manipulating the data and the model: a Python API, a command-line user interface, and a graphical user interface.Thus the software can fit hood filter into various data processing pipelines and requires only simple geometrical measures as input.
