Computer vision constitutes a dynamic and intricate field within computer science, where the aim is to imbue computers with the capacity to interpret and understand the visual environment, much like the human visual system does. This discipline is at the intersection of algorithmic innovation, machine learning, and artificial intelligence, enabling the analysis of images, videos, and other visual data sources to extract meaningful information or to initiate responsive actions.
Photos and videos are essential components of our modern society and serve as indispensable evidence in law enforcement, journalism, and science. However, the authenticity of these media is increasingly questioned due to manipulations and forgeries. One key technology to verify the genuineness of visual material is the analysis of shadows, a fascinating process that often unfolds like a gripping crime thriller. This technique examines the light sources and their interaction with the objects in the image to identify anomalies that could indicate manipulations.
Corpse stains, also known as livores, form a complex mosaic of discolorations that has left the forensic world in awe for centuries. These postmortem markings, which occur as blood accumulates in the lowest parts of the body after death, offer a treasure trove of information invaluable for determining the time of death and conducting extensive forensic investigations. But what exactly lies behind these enigmatic stains that appear like silent witnesses after a person’s passing?

Rauscher, a forensic expert. When Süddeutsche Zeitung and Der Spiegel approached me, I knew immediately that this task would be anything but ordinary.
