In an age of digital images, we have all become photographers. High-quality cameras in mobile phones, together with apps that send images to our contacts, have transformed the way in which we communicate. This talk will take a look at digital images and at some of the mathematics upon which many of the techniques for processing images are based. ========== The London Mathematical Society has, since 1865, been the UK's learned society for the advancement, dissemination and promotion of mathematical knowledge. Our mission is to advance mathematics through our members and the broader scientific community worldwide.
