本篇論文提出的整合式解交錯(Integrated De-interlacing)的演算法,可以有效提昇移
動區域的畫面,但是當移動估計不正確時,反而會使移動補償後的畫面變得很差,為了
改善這種情況,因此結合移動可適性解交錯的優點,並將空間圖場內插(Spatial
Interpolation)的方式改成ELA(Edge Line Average)來設計,經過電腦模擬的結果發現,不僅在視覺上提高畫面的解析度,在某些影像峰值訊號雜訊比(Peak Signal Noise Ratio ,

核磁共振(NMR)技术探测地下水是目前唯一的直接找水的地球物理方法。与传统的地球物理方法相比具有高分辨力,高效率,信息量丰富和解唯一性等优点。利用核磁共振地下水探测系统可以高效率地进行区域水文地质调查,确定找水远景区,圈定地下水在三维空间内的分布,进而可靠地选定水井位置等。但是由于水中氢核产生的核磁共振信号的幅度小(纳伏级),要求探测系统的灵敏度高,将引入大量的自然和人为噪声,导致采集信号的信噪比低,解释结果不清楚。
