Forensics and Computer Vision: Blood Spatter Analysis
/ November 21, 2017

Often found at the scenes of violent crimes, the analysis of bloodstains can provide vital clues as to the occurrence of events Bloodstain Pattern Analysis is a forensic discipline in which, among others, the position of victims can be determined at crime scenes on which blood has been shed. Therefore, we studied in details about blood spatter analysis and their pattern analysis in image processing system. Blood Spatter Analysis : Significance Some scenes of violent crime contain blood stains. Blood spatter stains occur when blood falls passively due to force being applied to a body. There is a well established though extremely tedious technique by which a specially trained forensic technician can analyze the individual blood spots. Blood spatter analysis is performed by forensics experts at crime scenes where impact on a body has caused blood to fly off and land on surrounding surfaces. The resulting stains are affected by many physical variables, such as speed, liquid density, and the material properties of the surface. However, the shape of the stains, in this case the spatter pattern, does reveal information that can be useful to investigators. Subsequent developments have led to the emergence of Blood Spatter Analysis as a forensic…
