As technology is brought to bear the latent finger prints and shoe prints recovery, the combination of existing technique will be joined with the new system to improve the recovery rate on traditionally difficult surfaces. The problem with collecting forensic evidence at a crime scene is that the evidence is often masked behind backgrounds. This makes it difficult for extracting key components from the evidence. Often times, the background color of the crime scene can overpower the faint detail of the evidence. Types of evidence that this can occur on is with finger prints and shoe prints at the crime scene. To correct this problem, image enhancement techniques can be used to obtain the relevant information that is needed for the investigators.
