  3. There are mainly two type of algorithms used for spatial spectrum estimation : one is those based on bayesian maximum likelihood method, like the ml ( maximum likelihood ) algorithm, maximum entropy method and etc., the others are based on the spatial decomposition or projection of correlation matrix, this kind of algorithm include vector characterization method, music ( multiple signal classification ) algorithm, projection matrix method, etc. music is a classical spatial spectrum estimation algorithm that has a super high resolution and is widely used today, however, it cannot estimate doa of signals that are correlated

    空間譜估計的演算法大致分兩大類:一是基於極大似然估計和最大后驗概率估計統計理論的演算法,包括:極大似然估計法( ml ) 、最大熵法等;另一類是基於對協方差矩陣進行子空間分解或投影的演算法,包括:矢量特徵法、多重信號分類法( music ) 、投影矩陣法等。其中, music法是一種經典的空間譜估計主流演算法,具有超強的分辨性能,但它無法實現對相干信號進行測向分辨。

  6. Aimed at static image retrieval based on color, a multimedia image database which included three layers was designed and the search algorithm of the correlation and polymerization histogram was used in the article. to show color characteristic of image, the method of the hsb ( hue, saturation, brightness ) color space, which is suitable to the visual characteristic of human, is utilized. taking advance of human ' s feeling to color, it quantifies color sector with unequal interval, and get characteristic vector

    針對基於顏色的靜態圖像檢索,本文設計了一個三層的多媒體圖像數據庫,選用基於相關聚合直方圖的演算法,採用符合人類視覺特徵的hsb顏色空間來表示圖像的顏色特徵,利用人對顏色的感知來對顏色分量進行非等間隔的量化並形成特徵矢量,用距離度量函數進行圖像的相似性匹配。
  7. Thirdly, a new method of resizing color image is presented, where the processing of color image data is carried out by using bivariate ( vector valued ) blending rational interpolation. this method is more effective on color image processing, because of the inherent correlation that exists between the image channels, and the nonlinearity among image pixels

    接著,從彩色圖像三基色之間存在相關性的角度出發,提出了利用二元(向量值)混合有理插值進行彩色圖像的縮放方法,該方法也可用於灰度圖像處理,此時向量有理插值處理轉為標量有理插值處理。
  8. The individual svm is prone to fail in the intrusion detection for the fragility of being attacked. this paper addresses a method using a support vector machines ensemble approach based on negative correlation learning for intrusion detection. using a correlation penalty term in the error function, the aggregate members can be accurate and diverse. and the evolutionary strategy is considered as the best way to automatically determine the individ. ual svms hyperparameters. at last we combine the results of all individual svms using ensemble technique. this distributed parallel detection can strengthen the robustness of the system. simulation results show the effectiveness of the method presented in this paper

    在入侵檢測中使用單個的支持向量機容易因"單點失效"而危害系統安全.提出一種基於支持向量機集成的方法來進行入侵檢測.它採用負相關學習技術,在誤差項中使用相關性懲罰因子使得生成的分類器有更好的多樣性和精度;演算法採用進化策略來自動地確定個體支持向量機的超參數,避免了需要了解問題的先驗知識;最後,採用集成技術來組合個體支持向量機的檢測結果.模擬實驗表明這一方法有更好的檢測性能,並且這種分散式并行檢測方法有利於增加入侵檢測系統的魯棒性
