optical invariant 中文意思是什麼
optical invariant
解釋
光學不變量-
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
為了保證opr系統有高的相關信噪比（ snr ）及良好的實時性能，本文對不同圖像預處理演算法的處理性能及效果進行了比較分析，為opr系統選取恰當的圖像預處理演算法提供了依據；將時間多重化技術與空間多重化技術相結合，設計製作了三維目標的可實時刷新的sdf參考濾波器庫，為opr系統提供了高snr的相關輸出，從而實現了opr系統對目標的實時畸變不變光學相關；將人工神經網路（ ann技術）用於相關信號后處理，有效提高了opr系統的識別效率。 -
