Abstract

A simple method for blood spatter analysis was implemented using an image processing technique. The advantages
of the computer application were exploited which subsequently provides minimal time consumed and user friendly interface.
The outputs from the program associated with the string method are used for finding the origin of the incident, i.e. where
the blood came from. The direction and the impact angle of the bloodstain use 4-step process analysis. The comparisons
between outputs from the program and the traditional method were reported. The primitive outputs from the program are
marginally acceptable with approximately 10% error; however, with a simple tweak manually, the errors drop more than three
times.
