  • Publication number: 20220351867
    Abstract: A computer-implemented method and a system for dating a blood pool lying on a substrate are described. The method comprises: determining, based on at least one picture of a blood pool lying on a substrate taken at a given time (t), the drying front of the blood pool at the given time (t); and determining, based on the determined drying front of the blood pool at the given time (t), and on a drying model, the time elapsed between the given time (t) and an initial time (t0) at which the blood pool initiated a drying process on the substrate. Determining the drying front of the blood pool comprises determining the wet perimeter (Pt) of the blood pool, and the drying model correlates the time elapsed with a blood's diffusion coefficient (Dblood) measured for a plurality of predetermined environmental conditions and a plurality of initial blood pool conditions.
