摘要:

掌纹识别是生物特征识别领域的前沿课题，其中非接触式的掌纹识别技术因其具有用户体验性好、无卫生污染等特点，日益成为相关研究领域的热点。但是非接触式的掌纹识别技术易受背景复杂、光照不足等不良因素的影响，给掌纹的图像采集与特征的提取匹配带来了困难。为了更好地解决这些问题，需要采用更为有效的图像增强技术。文中介绍了非接触式图像采集与预处理过程中图像增强技术的基本概念，对该技术实现方法进行了归类阐述和分析，探讨了该技术的发展趋势

Abstract:

Palmprint recognition is a leading subject of biometric identification. The contactless palmprint recognition has increasingly be-come a hot research field because of its good user experience,no pollution of health. But contactless palmprint recognition is susceptible to complex background,insufficient light and other adverse factors,which makes it difficult to match the palmprint image acquisition and feature extraction. In order to solve these problems,need to adopt a more effective image enhancement technology. Introduce the basic concepts of image enhancement in image acquisition and pre-processing of the contactless technology. The technical implementation methods are categorized and then described and analyzed respectively. Discuss the development trend of the technology
