This page is an appendix to my paper:

• Édouard Thiel     [ paper pdf 226k ; slides pdf 176k ]
  On the Validity of the Two Raster Sequences Distance Transform Algorithm.
  In DGMM 2022, Discrete Geometry and Mathematical Morphology, volume 13493 of Lectures Notes in Computer Science, pages 436-446, Strasbourg, october 2022.

Source code in Python language, licence CC-BY :

• chamfer2D.py : image class, weighted mask and distance transforms in 2D
• showWDT.py : show DTs passes for a weighted mask
• checkWDT.py : comparisons of parallel vs sequential DTs with weighted masks

Download the three files, then run python3 showWDT.py or python3 checkWDT.py to print help and see command line usage.
