At first glance, math and art might seem like total opposites — math is full of rigid rules while art is free-flowing and creative. But as different as the two can be, sometimes math can be the key to revealing secrets of art and seeing deeper into artworks than we otherwise could.
This came in handy when it came to solving a mystery tied to the masterpiece known as the Ghent Altarpiece. The Altarpiece is a 15th-century oil painting by the Flemish brothers Hubert and Jan van Eyck. It’s made up of more than a dozen different paintings with side panels on hinges so it can be opened or closed. On one panel, there’s an open book just centimeters tall with some barely visible text on it. Art historians were curious if it was a real text, but the words were completely illegible.
A team of mathematicians thought they might just be able to fix that. The main problem was that there were cracks running throughout the painting. Fortunately, they did not have to start from scratch. There are lots of digital image processing algorithms out there that can pick out little branchy patterns that kind of look like cracks, like blood vessels and medical images or rivers and roads and satellite images. One way to do this is by using something called convolutional filters. Generally speaking, a convolutional filter takes a plain image and applies some operation to all the pixels in that image. That process creates a modified image based on the original.
By using convolutional filters, the team was able to identify the cracks in the painting, fill them in, and make the letters clear again. This allowed them to decode the text in the painting and uncover its hidden secrets.
