Impact angle analysis of bloodstains using a simple image processing technique
暂无分享,去创建一个
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.
