巧用PHOTOSHOP修正变形指纹特征

Using Photoshop to Correct the Deformed Fingerprints

相关研究表明,指纹变形对比对结果的影响远大于模糊指纹,修正变形至关重要。笔者认为可在模拟情境下,由实验人员在同类客体相同部位以相同作用力方式留下实验指印,根据实验指印与捺印指纹之间特征点的偏移规律,用Phtoshop软件对原现场变形指印的特征进行修正,从而为侦破工作提供帮助。

Studies show that the effect of fingerprint deformation is much larger than that of fuzzy fingerprint, and the modification of such deformation is very important. The paper believes in the relatively accurate correction based on experimental investigation, namely in the simulation scenario, where a researcher leaves fingerprints in the same area with the same force on the similar object as the target object on the spot of the cases and uses Photoshop software to correct the deformed fingerprints left on the spot based the comparison between the experimental fingerprints and deformed fingerprints.
