Feature | Optical Projection Tomography: A light based technology for 3D visualisation
Imaging science plays a crucial role in a wide spectrum of science fields ranging from remote sensing and automated surveillance to medical and biological fields. X-rays, positron emission tomography (PET) [1] and magnetic resonance imaging (MRI) [2] are just few examples of how imaging technology has propelled medical science into the next level. At Umeå Center for Molecular Medicine, we have been exploring the use of a relatively young 3D imaging technique known as Optical Projection Tomography (OTP), which we have so far applied to the investigation of diabetes in mice.

Feature | Doctored image detection: a brief introduction to digital image forensics
The contemporary digital revolution has changed the way we access, manipulate and share information, but these advancements have also introduced critical security issues that shake people’s confidence in the integrity of digital media. Sophisticated digital technology and photo-editing software, such as Adobe Photoshop, are ubiquitous and have made the process of manipulating images to create forgeries a fairly accessible practice. As a result, trust in digital imagery has been eroded. Read More
