Abstract

To establish the time of death, it focuses on the detection and identification of body fluids at the crime scene, which /is a very important forensic model. There are many methods for estimating the time of death, which in medicine is called Livor Mortis. This paper is mainly focused on forensic medicine by determining the approximate time of death by collecting various bodily fluids. There are number of different approaches that affect the post-mortem appearance of the body. Here, as a first step in the investigation, photographs are taken to ascertain the change in skin color after death caused by the accumulation of blood. It has been noticed that skin color is due to predetermined hemoglobin and red chromospheres present in red blood cells called melanin. They are separated and grouped by an outstanding digital technology called 3D Filter Block Similarity Clustering (3-DFBSC), which is a very good approach for the proposed system where clustering is very easy. With these digital methods, cluster analysis plays an important role in the analysis of image matching methods with which it can establish the time of death with these digital methods.

Keywords
