Photoshop在印章印文检验鉴定中的综合应用

The Comprehensive Application of Photoshop in Identification of Stamp Impression

运用Photoshop图像处理功能对印章印文进行检验鉴定,可在一定程度上摆脱因鉴定人员主观原因和操作失误造成的鉴定结果偏差,从而提高鉴定效率。通过实验,先分别运用调整曲线、色阶、色相、饱和度以及删除颜色通道和设置黑场的方法对印章印文进行前期处理,再分别采用重叠比对、测量比对、画线比对、拼接比对等方法对其进行比对检验。对比几种检验方法得出结论的客观性和可靠性,探索总结出利用Photoshop对印章印文检验鉴定的可行性操作流程。

Using Photoshop image processing function to analysis and identification the seal and imprinting,can get rid of the error identification results caused by subjective reasons and the error deviation,to improve the identification efficiency.Through the experiment,first adopt adjusting curves,color,hue,saturation,and delete the color channel and set to black method to preparatory identification of imprinting,then use overlapping comparison,measure comparison,setting-out comparison,split joint comparison method to comparison test.At the same time,compare the objectivity and reliability of the conclusion,to explore and summarize the feasibility of using Photoshop in the operation process of seal inspection and appraisal.
