The feature parameter extraction methods of the underwater target are studied which can improve the performance of the underwater acoustic countermeasure equipments. several feature extraction methods such as the scale invariance feature extraction, target pole extraction fourier - mellin transform etc are investigated by computer simulations. the experimental results demonstrated the efficiency of these feature extraction methods in the applications of underwater target recognition
對多種特徵提取方法如目標相對不變尺度特徵提取、目標極點特徵提取、目標信號的傅里葉?梅林變換特徵提取等進行了模擬研究，結果表明了這些特徵參數提取方法的有效性，具有良好的應用前景。 -
Some new features such as ratio of centripetal moment, ratio of eccentric moment and ratio of inertial moment are introduced in this dissertation. these features have the properties of scale - invariance -, rotation - invariance and translation - invariance, and can be used well in depicting the linearized outline object
本文提出向心矩比、偏心矩比、慣性矩比概念，對線性化后的輪廓應用本文方法，既能較好地描述圖像目標，又具有旋轉、平移和尺度不變性。 -
In this paper, we propose an adaptive wavelet transform which possess the properties of translation and scale invariance. firstly, the original signal is adaptively renormalized using a scale function of an orthonomal wavelet and the first two moments of the signal. then, we decompose the renomalized signal according to the conventional discrete wavelet transform. as we prove, this adaptive wavelet transform is translation - and scale - invariant, and an efficient algorithm for calculating these wavelet coefficients, called adaptive wavelet invariant moments, is proposed. finally, we give experiment results for 2 - dimension digital signals ( images ) to verify our conclusion
本文提出了一種具有平移和尺度不變性的自適應小波分解新方法，該方法利用信號的一階、二階矩及正交小波尺度函數，先對信號進行自適應小波「重整」 .然後再對重整后的信號進行普通小波變換.本文證明這種自適應小波變換是平移和尺度不變的，並給出了計算自適應小波變換系數（稱為小波不變矩）的一種有效演算法.對二維數字信號（圖像）的實驗證實了我們的結論 -
