FaceBase Landmarking Software Instructions (2025 August)

These are the additional (to the facebase steps) steps taken to make the FaceBase automatic landmarking software work - https://www.facebase.org/resources/human/facial_landmarking/

Installations

  1. Matlab - https://www.mathworks.com/help/install/ug/install-products-with-internet-connection.html
  2. PyMeshlab - https://pymeshlab.readthedocs.io/en/latest/installation.html
  3. Install Statistics and Machine Learning Toolbox add-on in Matlab for the pdist function.

Steps taken

  1. Get_compute_many_Windows generates a now defunct command using meshlabserver.exe. This executable has been deprecated since 2020. We need to use PyMeshlab library in python instead.
  2. Use compute_curvature.py instead. This utility generates the curvature of each object .obj file and converts it into a .ply file with C information in it required by the landmarking method. Currently, if you open .obj file, you'll find V (vertices) and F (faces) information.

A simple llama index demo to query local files using OpenAI API.
# Import necessary packages
import os

"""
This script removes stray lines from images using image processing techniques with OpenCV library.
All credit where it's due - https://stackoverflow.com/a/45563349/4411757. Simon Mourier created a script in C# which I
have ported to python. Tested with python 3.5 and opencv-python==3.4.2.17. Shoot your suggestions/improvements in the
comments. Cheers!
