The image characteristics obtained by normal feature extraction generally have no stability appearing as variant positions on different intensity of illumination for the same scenery and analysis precision is seriously affected
常規的圖像特徵提取方法提取的特徵一般不具備穩定性，表現在不同光照條件下對同一景物拍攝的圖像提取的特徵的位置是不同的，這將嚴重影響三維景物分析的精度。 -

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。 -
