| Summary: | Recovery of shoe prints at crime scenes provides useful information in investigation
and act as valuable evidence of the crime. Unfortunately, most shoe print evidence
are placed aside due to the poor state of the evidence, absence of comparison
samples, and the lacking of knowledge and exposure towards such evidence. Many
recovered shoe prints at crime scenes are in low quality which contribute in the
difficulties of identification and comparison processes. Preservation and digital
forensic enhancement of shoe print images are essential in providing an increase
of the evidential value of such prints. The study builds on the utilisation of
commercially available image processing software Adobe® Photoshop® CC for the
forensic enhancement of shoe print images. Several shoe print images made on
different surfaces i.e. newspaper, rubber mat and carpets; were photographed using
a Canon EOS 40D Digital Single Lens Reflect (DSLR) camera. These shoe prints
were created using black ink stamp pad. The enhancement of the shoe print images
were performed using the Adobe® Photoshop® CC adjustment and filter tools which
include white balance, colour adjustment, and sharpen filters. The shoe print images
were successfully enhanced by either fully or partial reduction of the noise
background to contrast the prints from their backgrounds. The isolation of the shoe
prints from the backgrounds has improved the clarity of the shoe prints and therefore
aid in further comparison and identification analysis. |
