An image processing approach to blood spatter source reconstruction

Abstract

Blood spatter analysis is a part of Criminal Justice system and subpart of the forensic science. Traditional blood spatter analysis has a problem with the crime scene contamination. The crime scene contamination can led to the unacceptance of the evidences. The blood spatter analysis is the process which heavily relies on the expertise of the forensic scientist. The human intervention also creates the problem of errors and misjudgments. Use of image processing to the whole will deal with automation of removing human factor. The proposed method takes the image from blood spatter using image processing and reconstructs the source of the blood. The proposed methodology uses the Otsu’s method for thresholding and Hough transform for edge detection.
