痕迹图像的快速模糊增强算法及实现

Fastspeed Fuzzy Enhancement Arithmetic and Implementation of Mark Image

针对痕迹图像的增强处理实际需求 ,通过分析 Pal的对比度模糊增强算法的不足 ,给出了一种改进的快速模糊增强算法。该算法由于采用简化的隶属度函数和分段对比度模糊算子 ,较好地弥补了 Pal算法速度慢和丢失原图像中低灰度值信息的缺陷。实验结果表明 ,该算法对痕迹图像增强处理有着良好的效果 ,尤其是通过对分段模糊算子中 pij取值范围和变换方法的合理选择 ,可实现对痕迹图像进行局部的对比度增强 。

Aiming to practical purpose of mark image enhancement, through analysing the definition and speeding of the contrast fuzzy enhancement arithmetic (Pal),a fastspeed fuzzy enhancement arithmetic is offered based on simply function and the fuzzy segment operator of contrast ratio to consummate deficiency of Pal.Experiment concludes that the arithmetic is effective to mark image enhancement, especially rational choice of the range of p ij in fuzzy segment operator of contrast ratio and the method of mapping.
