Forensic Digital Image Processing: Optimization of Impression Evidence

商品描述

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.

 

 

商品描述(中文翻譯)

數位革命在過去幾十年中推進了證據檢測、攝影、優化和解釋的每一個面向。法醫科學家和從業者從膠卷轉向數位的過程中獲益良多。隨著適當程序的實施，數位影像和案件處理能力在複雜性和範圍上都大幅提升，這得益於各種工具的使用，這些工具能夠增強證據和攝影效果。

《法醫數位影像處理：印記證據的優化》為法醫調查員提供了提取、優化和解釋犯罪現場最大證據的工具和理解，以提高識別率。本書首先探討法醫數位影像處理的出現，以及在過去四十年中該科學的逐步改進和接受。內容涵蓋影像完整性和驗證的問題，包括法醫影像優化和影像操作。各章節探討利用色彩理論、模式和通道來優化影像中的信噪比的技術。

數位影像技術的一大優勢是能夠將同一主題的多個影像結合起來，創建最終的混合影像：這種影像顯示所需的證據，對於指紋或鞋印特別有用。後面的章節展示了影像減法、焦點堆疊和高動態範圍，利用最佳對焦的影像，並減少或完全消除基材干擾。作者將快速傅立葉變換視為去噪的最佳工具，並探討噪聲特徵的基本理論和診斷。本書還討論了數位影像技術的歷史及其在法庭系統中的處理。

《法醫數位影像處理：印記證據的優化》作為一個寶貴的資源和工具，為實務專業人士以及新進入該領域的人士提供最佳實踐、最新技術和利用日益增多的行業工具的進展。

作者簡介

Brian E. Dalrymple, CLPE began a career in identification in 1971 with the Ontario Provincial Police, Forensic Identification Services, Canada. In 1977 he co-developed the technique of evidence detection with argon lasers through inherent fluorescence and became the first in the world to operate a laser for evidence detection in criminal cases. The extensions of this technology are now in global use and have provided pivotal evidence in hundreds of major investigations. In 1991, as Associate Section Head, he introduced the first Computer Evidence System to Canada, and later became the first Canadian to tender expert evidence in this emerging technology. In 1992 he was promoted to Manager, Forensic Identification Services, a position he held until his retirement in 1999. He initiated and co-wrote the Body Examination Protocol for the Province of Ontario, regarding the examination of murder victims for fingerprints on skin. Brian Dalrymple has taught extensively in North America, China, the Middle East and Australia. He is the recipient of the John Dondero Award (1980, IAI), the Award of Merit (1980, Institute of Applied Science), the Foster Award (1982, the Canadian Identification Society) and the Lewis Minshall Award (1984, the Fingerprint Society, UK). Brian has been a contract instructor for the Ontario Police College for more than a decade, and provides forensic consulting for police agencies, attorneys and the corporate sector. With Ron Smith & Associates, he is a consultant and staff instructor working as part of a team forensic experts. He is an Adjunct Professor at Laurentian University in the Forensic Science Department.

 

 

Jill Smith is an Imaging Specialist with the York Regional Police in Ontario Canada, working in forensic computer image analysis enhancement for fingerprints, footwear, bite marks, and other evidence. She keeps up on the latest technology and trains others in Adobe Photoshop techniques. Jill was a guest lecturer at the Ontario Police College for ten years and had co-taught fingerprint technique courses with Brian Dalrymple. She has been published in industry journal publications including several times in the IAI's Journal of Forensic Identification.

 

 

作者簡介(中文翻譯)

Brian E. Dalrymple, CLPE 於1971年開始在加拿大安大略省警察局的法醫識別服務部門展開識別職業生涯。1977年，他共同開發了利用氬激光進行證據檢測的技術，並成為全球首位在刑事案件中操作激光進行證據檢測的人。這項技術的延伸目前已在全球範圍內使用，並在數百起重大調查中提供了關鍵證據。1991年，作為副部門負責人，他將第一個計算機證據系統引入加拿大，並成為首位在這一新興技術中提供專家證據的加拿大人。1992年，他晉升為法醫識別服務部經理，並在1999年退休之前一直擔任此職位。他啟動並共同撰寫了安大略省的屍體檢查協議，針對謀殺受害者皮膚上的指紋檢查。Brian Dalrymple 在北美、中國、中東和澳大利亞進行了廣泛的教學。他曾獲得約翰·唐德羅獎（1980年，IAI）、優異獎（1980年，應用科學學會）、福斯特獎（1982年，加拿大識別學會）和路易斯·敏肖獎（1984年，英國指紋學會）。Brian 在安大略省警察學院擔任合同講師超過十年，並為警察機構、律師和企業界提供法醫諮詢服務。與Ron Smith & Associates合作，他作為顧問和員工講師，成為法醫專家團隊的一部分。他是勞倫森大學法醫科學系的兼任教授。

Jill Smith 是加拿大安大略省約克區警察局的影像專家，專注於法醫計算機影像分析增強，處理指紋、鞋印、咬痕及其他證據。她緊跟最新技術，並訓練他人使用Adobe Photoshop技術。Jill曾在安大略省警察學院擔任十年的客座講師，並與Brian Dalrymple共同教授指紋技術課程。她在行業期刊上發表過多篇文章，包括多次在IAI的《法醫識別期刊》上發表。
