New experimental results for scale-invariant implementations of the binary phase-only matched filter and the nonlinear joint transform correlator using ferroelectric liquid-crystal spatial light modulators are presented. We provide a comparative study of both architectures for real-time road-sign recognition. Signal-to-peak-noise ratios in excess of 5 dB over a scale range of 1.0 to 2.0 are achieved under realistic conditions of clutter.
给出了使用铁电液晶空间光调制器实现二值纯相位匹配滤波器和非线性联合变换相关器的尺度不变实验结果。我们对这两种用于实时道路标志识别的架构进行了比较研究。在实际杂波条件下，在1.0至2.0的尺度范围内实现了超过5 dB的信号峰值噪声比。
