2D/3D距离选通成像的低对比度目标探测
距离选通成像 低对比度目标 三维成像
2016/8/24
低对比度目标探测在司法取证、反恐维安、远距离监控、搜救等应用中具有重要意义，然而传统二维成像方法则难以对其有效探测。由此，提出了基于2D/3D 距离选通成像探测低对比度目标的方法：通过2D 距离选通成像直接获取目标无背景或背景部分滤除的二维选通图像，从而突显目标，简化目标提取图像处理；当复杂背景无法有效滤除时，可进一步通过3D 距离选通成像重建二维选通图像中丢失的三维空间信息，通过距离图区分目标与...

人眼在自然张开状态下，虹膜区域会受到部分眼睑、睫毛的遮挡，这些噪声会降低虹膜识别的准确性，因而在识别时应该尽可能将虹膜有效信息提取出来，而将眼睑、睫毛等干扰去除。为此本文提出了一种在归一化后的虹膜图像上利用2D-Gabor滤波器检测和去除虹膜区域内噪声的方法，并将噪声区域标记。在虹膜匹配时，通过将虹膜代码中的干扰位去除来尽量避免噪声对于虹膜识别的影响。实验结果表明本文提出的方法可以准确检测并标记噪...
