摘要
本文证明了两个基本定理。在假定图象信号和附加噪声是相互独立的零均值齐次高斯随机场、且二次可微的条件下,解决了平均绝对差图象匹配系统的定位精度的分析和计算问题。用实例说明了精度分析和计算的方法,分析了影响定位精度的因素和参数。为匹配性能的定量分析提供了理论依据和方法。
Two basic theorems are proved in this paper. Suppose the image signal and the superposed noise are mutually independent homogeneous Gaussian random field with zero mean and both are (twice) differentiable, the analysis and computation problems of the local accuracy of mean absolute difference image matching systems are solved. The theoretical basis and method of quantitative analysis are provided for matching performance. The factors and parameters which have effects on the local accuracy ate illustrated by examples.
