- 最小邻域均值投影函数及其在眼睛定位算法.提出一种投影函数：最小邻域均值投影函数．该函数通过计算每条投影线上各像素点邻域均值的最小值 来跟踪图像中的低灰度特征．与传统的积分投影函数和方差投影函数相比，它以求最小值的局部选择性代替传统投 影函数的全局累加性，因此具有对片状噪声不敏感的特点、此外，在计算过程中，它还能记录最小值点的二维位置信 息，是一个二维的搜索算子、最小邻域均值投影函数的这些特点使其非常适合于眼睛定位．它对眼睛，特别是瞳孔，总 能够产生精确、鲁棒的响应通过在CAS—P

- 创建一个计时测试程序，比较公式节点和本地LabVIEW数学函数的平均执行时间。此程序需要一个For循环或一个平序或叠序结构以及一个Case结构。要求For循环运行计时测验N次，然后使用Statistics Express VI对结果做平均。要求顺序结构在代码运行之前以及代码运行之后对Tick Count进行采样。要求Case结构判定用户是要执行公式节点还是要执行本地LabVIEW数学函数。对每个分支运行计时测验程序。哪种方法执行时间最快？哪种方法最容易编程？别人要看程序时，哪种方法更容易理解-T

- 由于光线分布不均匀或斑块噪音干扰等原因,往往使所要处理的指纹的灰 度值分布缺乏均匀性。在指纹特征自动识别提取过程中,造成许多传统的算法在局部出 现很大的误差。利用方差和均值特征的自动提取方法,首次对不均匀灰度图像进行自适 应分割。然后通过对图像分区域进行不同程度的自适应调整,使具有相同属性的像素单 元具有近似的灰度值分布。调整结果的灰度均匀水平与预先指定的调整精度成正比。这 种调整不仅提高了图像分割的自适应性,而且进一步扩大了一般阈值算法的应用领域。-Gray value d
