• Abstract: Objective: To investigate the application method and processing effect of Photoshop software in difficult fingerprint image processing, and provides a software processing method for fingerprint image enhancement technology. Methods: In Photoshop CC 2017 software, the difficult fingerprint image is optimized by adjusting the brightness/contrast/curve/color scale, channel difference calculation, high-contrast retention and sharpening, the overlapping fingerprint and fuzzy fingerprint are identified, and the fingerprint image on monochrome background and complex background is enhanced. Results: Photoshop software can identify difficult fingerprints well. The processed fingerprint features are obvious, and the recognition degree of monochromatic background fingerprint image is high. Conclusion: Photoshop software can improve the evidence characteristics of fingerprint image, its effect is obvious, the result is accurate, can be applied to the identification of difficult fingerprint. 目的：考察Photoshop 软件在疑难指纹图像处理中的使用方法和处理效果，为指纹图像增强技术提供可以借鉴的软件处理方法。方法：采用Photoshop CC 2017 软件，通过调整亮度/ 对比度/ 曲线/ 色阶、通道差值计算、高反差保留和锐化等方法，对重叠指纹和模糊指纹进行识别、对单色背景和复杂背景上的指纹图像进行增强处理。结果：Photoshop 软件能够很好地对疑难指纹进行识别，处理后的指纹特征明显，且对单色背景指纹图像的辨识度较高。结论：Photoshop 软件能够提高指纹图像的证据特征，其效果明显、结果准确，可以应用于疑难指纹的识别中。
