Abstract : the characteristics of wavelet transform and its significance in image edge extraction are presented. the detailed steps for the extended target centroid calculation with wavelet transform are described. extracting target ( airplane ) centroid coordinates when airplane images are in the background noise conditions with different image fuzzy degrees by using wavelet transform, the extracting accuracy for target centroid coordinates under the different image fuzzy degrees and background noise conditions are compared. the application prospect of wavelet transform in the extended target tracking is shown
文摘:介紹了小波變換的特點及其在圖象邊緣提取中的意義,說明了擴展目標用小波變換進行目標形心計算的詳細步驟,並以飛機圖象為目標在不同圖象模糊程度及背景噪音情況下用小波變換進行了目標形心坐標提取,比較了不同圖象模糊程度及背景噪音情況下目標形心坐標提取的精度,展示了小波變換在擴展目標跟蹤技術中應用的前景。Aircraft noise and flight tracks are also monitored around the clock by a computer - based aircraft noise and flight track monitoring system
