Abstract: Objective The image processing software can help us analyze the authenticity of the photo contents,and it also supplies us a number of technical methods to identify some doctored photos.Method We can process and analyze the photo contents by Photoshop CS2 or Ever-spry trace test/document examination image processing system.Result Two parts of the photo contents which present a multiple corresponding feature points and a large area of overlap pseudo-color image,and that violate the law of nature,so it is a composite photo.Conclusion Ever-spry trace test/document examination image processing system which is powerful and convenient not only provides a strong support to the trace test/document examination,but also offers the conditions for the image examination and identification.

Key words: image processing, photomontage, identification

摘要： 目的通过运用软件分析鉴别照片内容的真伪,为伪造图片的鉴定提供一些技术方法。方法分别运用PhotoshopCS2和恒锐痕检/文检图像处理系统中的一些功能对照片中的内容进行处理分析。结果照片中两部分内容所呈现出的多处特征点的对应和其伪彩色影像的大面积重合,不符合自然规律,系复制合成照片。结论恒锐痕检/文检图像处理系统强大而简便的功能不仅为痕检、文检工作提供了强有力的支持,也为影像的检验鉴定提供了条件。
