Two block time - recursive algorithms are developed for the efficient and fast computation of the 1 - d rdgt coefficients and for the fast reconstruction of the original signal from the coefficients in both the critical sampling case and the oversampling case. the two algorithms are implemented respectively by a unified parallel lattice structure. and the computational complexity analysis and comparison show that the proposed algorithms provide a more efficient and faster method for the computation of the discrete gabor transforms
首先論證了一維rdgt系數求解演算法和由變換系數重建原信號演算法，不論是在臨界抽樣條件下還是在過抽樣條件下，都同樣具有塊時間遞歸特性，並提出了相應的塊時間遞歸演算法及其并行格型結構實現方法，計算機模擬驗證了并行格型結構實現的可行性，計算復雜性分析與比較也說明了rdgt塊時間遞歸演算法的并行格型結構在計算時間方面所具有的高速和高效性能。 -
Many kinds of filters are presented in this paper, e. g. adaptive transversal filter ， direct two - order iir filter, lattice iir filter, high - order iir filter and adaptive sampling filter. because these filters have some limitations and defects, the adaptive filter of other structure is discussed in the paper
論文研究了窄帶干擾抑制的幾種濾波技術，主要有自適應橫向濾波器、直接結構的二階iir型濾波器、格型結構的iir型濾波器、高階iir濾波器以及自適應采樣濾波器。 -
As a result, digital images usually suffer from aliasing due to undersampling, loss of high - frequency detail due to relative motion or out - of - focus. supperresolution involves up - conversion of the input sampling lattice as well as reducing or eliminating aliasing and bluring
因此，通常數字圖像因欠采樣（ undersampling ）而引起的信號混疊，因低解析度傳感點擴散（ psf ： pointspreadfunction ）而造成的高頻部分、丟失，以及因相對運動或散焦造成的光學模糊等因素而受損。
