Spotting gaps in centuries-old texts using… maths

About the research

Imagine a centuries-old university library. Damp air, insects, and books full of tiny holes caused by the ravages of time 🐛📖 It sounds harmless, but for text recognition software it’s a disaster: a tiny hole just before the word ‘book’ and suddenly the computer reads ‘oboek’ 😅

Fortunately, there’s… maths! VUB researcher Quinten Van Boxstael has developed a method, based on wavelets – a kind of mathematical microscope – to detect those holes in advance. The result: digitising thousands of old books more quickly and accurately, ensuring that knowledge is preserved for the future.

Quinten explains it all with infectious enthusiasm in the video.

Quinten Van Boxstael became interested in mathematics when a classmate in sixth grade mentioned the Pythagorean theorem. When he looked up this theorem that evening, he was utterly fascinated by the fact that, through logical reasoning, one can prove a result that applies to all right-angled triangles. This universal nature of mathematics and the beauty of careful reasoning convinced him to study mathematics at Ghent University in 2019. During his studies, he enjoyed solving concrete mathematical problems using abstract methods. This led him to complete a PhD at the VUB in 2024, in which he uses methods from functional and harmonic analysis to solve concrete problems in mathematical analysis and beyond.
