  4. 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。
  5. First, resistance to geometrical distortion was obtained by using moment normalization ; second, we focus on the phase of fourier - mellin transform. before detecting watermark, synchronization could be retrieved by using the phase information. to eliminate the influence of pixel value distortion generated during print / scan process, a dft - based robust watermark algorithm was designed, which could successfully detect watermark from a severe distorted image

    另一種思路是根據圖像經過旋轉、縮放、平移后，其傅立葉?梅林變換域只有相位受到影響的特點，從其相位中提取幾何失真信息，然後再進行相應的失真補償，從而消除幾何失真的影響；對于列印掃描過程產生的像素值失真，本文也提出了一種基於dft的魯棒性演算法，能在較嚴重的圖像失真情況下，成功檢測水印。

    研究了連續小波變換的計算結構，給出了基於fft和mellin變換的兩種連續小波變換快速演算法，為寬帶相關處理的快速實現提供了基礎。
  8. Finally, we recover the watermark according to encodement. we also apply the novel detection strategy into the image watermarking algorithm based on fourier - mellin transformation, which is trong to geometric invariants

    提出了構造和提取「零水印」的演算法： 「零水印」是利用圖像的重要特徵來構造水印信息，而不修改原始圖像的任何數據。
  9. The mellin rapid compute method is given. the analog or analog - digital mixed versus digital circuit used to perform wt has been discussed. also discussed the methods on how to realize the cwt both in time - domain and frequency - domain

    第二章討論了小波變換的定義及分類，回顧了小波變換的思想，給出了小波變換的主要特點及幾種常用的基本小波。
  10. In this paper it is founding that at the aspect of extracting characteristic information of the pulse signals, the usual algorithm of the cwt has better superiority than the algorithm based on the discrete mellin transform

    在分析中發現，在提取吸毒者脈象信號中病變的異常信息方面，連續小波變換的一般演算法比藉助離散梅林變換的演算法具有更好的效果。
  11. By means of the x - y scheme and three - dimensional of the cwt, finding the significant difference between the heroin addicts and the healthy persons, a primary criterion was obtained. upon which the 15 heroin addicts were identified and 2 healthy persons were misjudged. this paper have deduced and proved the theorems and formulas of the discrete mellin transform, and applied the cwt which based on the discrete mellin transform to analyze the pulse signals of 15 heroin addicts and 15 healthy persons

    通過連續小波變換的二維及三維立體圖，找出海洛因吸毒者與正常人之間的顯著差異，並對每種基本小波的分析給出了初步的判據，根據該判據，獨立地給出了相同的判斷，均為正常人z01和z10被誤判為吸毒者，而15例吸毒者全被檢測出來。
