An invitation to the Euler characteristic transform

E Munch - The American Mathematical Monthly, 2025 - Taylor & Francis
The Euler characteristic transform (ECT) is a simple to define yet powerful representation of
shape. The idea is to encode an embedded shape by tracking how the Euler characteristic …
