Notebooks

The notebooks/ directory contains interactive Marimo notebooks. Unlike Jupyter notebooks, Marimo notebooks are pure Python files: they are versionable, reproducible (no hidden state, reactive execution), and runnable as scripts.

Running the notebooks

pip install -e .[dev]          # installs marimo
marimo edit notebooks/dictionary_matching.py   # interactive editing
marimo run notebooks/dictionary_matching.py    # read-only app mode
python notebooks/dictionary_matching.py        # plain script execution

Available notebooks

cgpt_pipeline.py

The forward and inverse problem step by step: build a shape, place an acquisition system, simulate the MSR matrix, reconstruct the CGPT and compare it with the theoretical value and with the closed-form ellipse formulas.

dictionary_matching.py

The complete identification experiment of the FoCM 2014 paper: a dictionary of shapes, an unknown (transformed) target, noisy measurements, and identification by invariant shape descriptors — including a study of the robustness to noise.

target_tracking.py

Tracking of a moving target with the Extended Kalman Filter: simulate a random trajectory, generate the stream of noisy MSR matrices, and estimate position and orientation online.
