摘　　要：重叠手印的分离是刑事技术工作的关键环节,是保证指纹自动识别和检验鉴定工作顺利进行的前提。梳理、对比和分析了现有重叠手印分离方法,包括套描分离法、套色分离法、Photoshop分离法、光学分离法、明胶胶片分离法、计算机处理法和化学成像法,并对重叠手印分离的研究方向进行了展望。精准分离各类现场重叠手印对于提高手印证据的利用率、维护司法公正具有重要意义。Overlapped fingermarks are often encountered at crime scenes.The separation of overlapped fingermarks usually plays an important role in forensic investigation since the automatic or manual fingerprint comparison and identification rely critically on the recovery of the sufficient ridge details from the two fingermarks.The separation methods including methods of copy tracing separation,color tracing separation,Photoshop separation,optical separation,gel-lifter separation,computer separation and chemical imaging are reviewed and analyzed.Future research and development of the separation of overlapped fingermarks are summarized.A increasing usage of fingerprint evidence,as well as the improvement of justice against crime can be expected.
