Spotting gaps in centuries-old texts using… maths
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 in the word ‘book’ and suddenly the computer reads ‘oboek’. Fortunately, there’s… maths! Quinten Van Boxstael explains how he uses wavelets – a sort of mathematical microscope – to detect those holes in advance, so that we can digitise books quickly and accurately.
