TOWARD AUTOMATIC BLOODSPATTER ANALYSIS IN CRIME SCENES

Amy R. Shen, Gabriel J. Brostow and Roberto Cipolla

June 2006

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 analyse the individual blood spots. This procedure estimates the body's 2D location on the floorplan when the body was impacted. Our image analysis algorithm contributes an automatic and accessible alternative that could be exploited at crime scenes, assuming the stains are known to be the result of spatter. This paper presents our approach and the results of comparative experiments we used to confirm the accuracy of the algorithm.

If you have difficulty viewing files that end '.gz', which are gzip compressed, then you may be able to find tools to uncompress them at the gzip web site.

If you have difficulty viewing files that are in PostScript, (ending '.ps' or '.ps.gz'), then you may be able to find tools to view them at the gsview web site.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
