摘要

本文研究了随机相位空间采样对光学字符识别过程的影响。我们首先对一维模式进行详细的分析。实证数据表明，我们的模型是准确的。然后，我们给出了更复杂的二维模式(即打印、扫描字符)的实验结果。空间采样似乎解释了实践中所见的大量可变性。

Spatial sampling effects in optical character recognition

In this paper we examine the effects of random-phase spatial sampling on the optical character recognition process. We start by presenting a detailed analysis in the case of 1-dimensional patterns. Empirical data demonstrate that our model is accurate. We then give experimental results for more complex, 2-dimensional patterns (i.e. printed, scanned characters). Spatial sampling seems to account for a significant amount of the variability seen in practice.
