Is that iteration times are not affected by the map s capacity 的一個優(yōu)點是迭代次數(shù)不受映射表容量的影響。
When iteration times are over 303, the computing accuracy is over 當?shù)螖?shù)大于300時,計算精度達到以上。
Listing 1 shows an example that measures the iteration time of a collection using the standard approach 清單1顯示了一個測量用標準方式遍歷集合所用時間的例子:
Thus, it is very difficult to decode the hashing algorithm; the security is enhanced via using the selected matrix and iteration time as the secret keys 將所選用的矩陣和迭代次數(shù)作為浮水印的密鑰,提高了算法的安全性。
The experimental results of reconstruction from computer-generated projections and real missile tomography projections show that the fast algorithm guarantees the fitness to original image, speeds the iteration time, and can be specially used for reconstruction for incomplete projections in fan scanning 利用模擬投影數(shù)據(jù)和實際導彈斷層掃描數(shù)據(jù)進行圖像重建,結果表明,與卷積反投影和代數(shù)重建法相比,此算法特別適用于扇形掃描的不完全投影數(shù)據(jù)的圖像重建,在保證重建圖像擬合度的同時,大大提高了重建速度。
