reference filter meaning in Chinese

基准滤波器

By comparing the image - preprocessing results of different processing algorithms , an optimized algorithm was decided to ensure satisfying correlation snr and preprocessing rate to be obtained . synthetic discriminant function ( sdf ) filters of the 3 - d targets were designed and the reference filter libs ( rfl ) were constructed to provide high correlation snr . real - time distortion - invariant optical correlation was realized by temporal - spatial multiplexing technique
为了保证opr系统有高的相关信噪比( snr )及良好的实时性能，本文对不同图像预处理算法的处理性能及效果进行了比较分析，为opr系统选取恰当的图像预处理算法提供了依据；将时间多重化技术与空间多重化技术相结合，设计制作了三维目标的可实时刷新的sdf参考滤波器库，为opr系统提供了高snr的相关输出，从而实现了opr系统对目标的实时畸变不变光学相关；将人工神经网络( ann技术)用于相关信号后处理，有效提高了opr系统的识别效率。
