Image analysis

PhD student Thomas Vogt tells us about his work in brain imaging.

How to make images out of ripples of pixels...

The maths behind music has inspired software that can merge faces.

Taming big data – Carola-Bibiane Schönlieb tells us about a new institute researching the mathematics of information

From cancer treatments to counting trees: the maths behind image analysis makes it all possible.

Carola tells us about her work in the field of image analysis, her favourite mathematical moments, and why creativity is so important in maths.

Stanley Osher has won the 2014 Gauss Prize for his revolutionary impact in areas including medical imaging, sonic booms, movie animation and microchip design and

Recent discoveries have made it possible to control computer games by thought alone, or work out what kind of item someone is thinking about from their brain signals. And that's not all. Researchers were able to use brain scans to reconstruct what someone was looking at. In these experiments the scientists were literally able to see what people were thinking. A worrying thought, perhaps. But how did they do it?
In 1979 decorating work in a house in Vienna revealed a set of medieval frescoes depicting a cycle of songs by a 13th century poet, who was particularly fond of satirising the erotic relationships between knights and peasant maidens. The frescoes are of great historical significance, but they are badly damaged. In this article Carola Schönlieb explores how mathematicians use the heat equation to fill in the gaps.
Not so long ago, if you had a medical complaint, doctors had to open you up to see what it was. These days they have a range of sophisticated imaging techniques at their disposal, saving you the risk and pain of an operation. Chris Budd and Cathryn Mitchell look at the maths that isn't only responsible for these medical techniques, but also for much of the digital revolution.
