The digital revolution over the past several decades has advanced
every facet of evidence detection, photography, optimization, and
interpretation. Forensic scientists and practitioners have
benefited tremendously from the move from film to digital. With
proper procedures in place, digital images and casework
capabilities have increased tremendously in both complexity and
range due to a vast array of tools to enhance evidence and
photography. Forensic Digital Image Processing: Optimization of
Impression Evidence provides the forensic investigator with the
tools and understanding to extract, optimize, and interpret the
maximum evidence possible from crime scenes to increase
identifications. The book begins by examining the emergence of
forensic digital image processing, and the gradual improvement and
acceptance of the science over the past four decades. Coverage
includes looking at the issues of image integrity and
authentication including forensic image optimization and the
manipulation of images. Chapters explore techniques exploiting
color theory, modes, and channels to optimize signal-to-noise ratio
in images. One of the greatest assets of digital image technology
is the ability to combine multiple images of the same subject to
create a final, blended image: one that displays the desired
evidence and is especially useful for fingerprint or footwear
impression. Later chapters demonstrate image subtraction, focus
stacking, and high dynamic range, utilizing images in optimum focus
and with substrate interference diminished or removed entirely. The
authors look at fast Fourier transform as an optimal tool for noise
removal, addressing basic theory and diagnosis of the noise
signatures. The book discusses the history of digital imaging
techniques and their treatment within the court system. Forensic
Digital Image Processing: Optimization of Impression Evidence
serves as an invaluable resource and tool for practicing
professionals-as well as those new to the field-to look at best
practices, the latest technology, and advances in utilizing the
increasing array of tools of the trade.
