Optical correlation schemes based on a matched filter containing a single logarithmic harmonic of an object are described. This correlator can provide shift and projection (tilt) invariant pattern recognition. The logarithmic harmonics, their orthogonality, and their completeness are presented, as well as experimental results using computer simulations and real optical targets. The projection invariance and the discrimination ability of this filter are successfully demonstrated.
描述了基于包含物体单个对数谐波的匹配滤波器的光学相关方案。这种相关器可以提供平移和投影（倾斜）不变的模式识别。介绍了对数谐波、它们的正交性和完备性，以及使用计算机模拟和真实光学目标的实验结果。成功证明了该滤波器的投影不变性和辨别能力。
