    The digital skeleton in modern video analysis - inter- and intraspecific comparsionofindividualrigs

    New methods for identifying individuals based on their digital skeleton (rig) gain attention in digital forensics. To ensure a solid comparison, understanding the development of this digital skeleton is crucial. One approach is manually creating a rig using a parametrized 3D room and cameras with embedded pictures, capturing multiple angles of the same person with markers on defined spots. Using these pictures and the room, a movable marker-based rig can be built in software like Blender (https://www.blender.org). It can be used to fit the rigged doll into another scene or compare proportions. For a similar process, algorithm-based software like OpenPose (https://github.com/CMU- Perceptual-Computing-Lab/openpose) estimates a digital skeleton from pictures or videos. The output includes JSON files with joint coordinates and pictures with embedded skeletons, which can manually be processsed into a rig. While these procedure can save time and expand applications, precision and supervision differ from marker-based rigs. A comparative study assessing similarity is discussed in the following paper.

    Kein Fingerabdruck? Kein Problem. Durch digitale Skelette ergeben sich in der modernen Videoanalyse ganz neue Möglichkeiten, um Personen zu identifizieren. Die Forscherin Elena Pistorius beschreibt, wie sie und das Team vom Forensic Science Investigation Lab diese nutzen, um Verdächtige virtuell auf einem Tatort zu platzieren und sie mit Aufnahmen von Überwachungskameras abzugleichen.
