The image processing by computer analysis has established a data base for applications in the industrial world. Testing has proved that the same system can provide documentation and evidence in all facets of modern day life. The medicolegal aspects in civil and criminal litigation are no exception. The primary function of the image processing system is to derive all of the information available from the image being processed. The process will extract this information in an unbiased manner, based solely on the physics of reflected light energy. The computer will analyze this information and present it in pictorial form, with mathematical data to support the form presented. This information can be presented in the courtroom with full credibility as an unbiased, reliable witness. New scientific techniques shown in the courtroom are subject to their validity being proven. Past imaging techniques shown in the courtroom have made the conventional rules of evidence more difficult because of the different informational content and format required for presentation of these data. I believe the manner in which the evidence can now be presented in pictorial form will simplify the acceptance. Everyone, including the layman, the judge, and the jury, will be able to identify and understand the implications of the before and after changes to the image being presented. In this article, I have mentioned just some of the ways in which image processing by computer analysis can be useful in civil and criminal litigation areas: existing photographic evidence; forensic reconstruction; correlation of effect evidence with cause of evidence; medical records as legal protection; providing evidence of circumstance of death; child abuse, with tracking over time to prevent death; investigation of operating room associated deaths; detection of blood at the scene of the crime and on suspected objects; use of scales at the scene of the crime; providing medicolegal evidence beyond today's technology; and a new theory and technique on using polygraph information in litigation. I am sure that the professionals in the forensic field will be able to think of many more applications where the image processing by computer analysis tool will be able to provide solutions to complex problems. The next time you say to yourself, "I wish they would have preserved this," or, "It's too bad they didn't do an autopsy," think of this new tool that is available to help you get the documentation and answers that will stand up to the scrutiny of the civil and criminal litigation system.
通过计算机分析进行的图像处理已经为工业领域的应用建立了一个数据库。测试证明,同一个系统能够在现代生活的各个方面提供文件和证据。民事和刑事诉讼中的法医学方面也不例外。图像处理系统的主要功能是从正在处理的图像中获取所有可用信息。该过程将仅基于反射光能的物理原理,以无偏见的方式提取这些信息。计算机将分析这些信息,并以图像形式呈现,同时提供数学数据来支持所呈现的形式。这些信息可以作为无偏见、可靠的证人在法庭上以完全可信的方式呈现。在法庭上展示的新科学技术需要证明其有效性。过去在法庭上展示的成像技术由于呈现这些数据所需的不同信息内容和格式,使得传统证据规则变得更加困难。我相信现在以图像形式呈现证据的方式将简化其被接受的过程。每个人,包括外行、法官和陪审团,都将能够识别并理解所呈现图像前后变化的含义。在本文中,我仅提及了通过计算机分析进行图像处理在民事和刑事诉讼领域有用的一些方式:现有的摄影证据;法医重建;效果证据与原因证据的关联;作为法律保护的医疗记录;提供死亡情况的证据;虐待儿童,长期跟踪以防止死亡;对手术室相关死亡的调查;在犯罪现场和可疑物体上检测血迹;在犯罪现场使用秤;提供超越当今技术的法医学证据;以及在诉讼中使用测谎仪信息的新理论和技术。我确信法医领域的专业人员能够想到更多应用场景,在这些场景中,通过计算机分析工具进行的图像处理将能够为复杂问题提供解决方案。下次当你对自己说“我希望他们当时保留了这个”,或者“他们没有进行尸检太可惜了”时,想想这个可用于帮助你获取能够经得起民事和刑事诉讼系统审查的文件和答案的新工具。
