  2. Then, the thesis presents a schema based two - level associated model, which dramatically reduces the number of the candidate subscriptions. in addition, an incremental subscription matching algorithm is proposed to efficiently matching events for millions subscriptions. furthermore, since indexing is very important to the system, the indexing scheme for xml data is defined based on the containment relationship, which can be more efficient to deal with relative paths than previous methods

    另外，由於在意向匹配過程中涉及大量索引問題，為此針對先前研究在處理基於相對路徑的意向表示上存在的問題，本文提出了一種基於相容關系的索引模式，利用系統抽象數據拓撲結構進行相對路徑到絕對路徑的轉換，通過基於相容關系的數字方式編碼，能夠快速確定對應結點的依賴關系，同時提出了新的路徑轉換演算法，將時間復雜度由過去的平方時間變為線性。
  3. Finally, a new 3d surface ranging method based on a digital fringe projection and shifting technique is systematically studied and non - linear rectification algorithms which reduce measurement error is proposed. at the same time, the noise - immune phase unwrapping algorithm is deeply studied and a new algorithm for phase unwrapping of phase map is proposed. experiment make known the algorithm can reduce measurement error, bypass the noise points automatically, solve the problem of the shade sheltering or cavity, overcome the error propagation problem and better results have been obtained

  5. Nowadays, digital image processing has been an important part of information processing, in numerous applications, especially in astronomy 、 medicine 、 military fields, the authenticity of image data is highly required. but in many image processing systems, image degradation is inevitably avoided owing to image transmission and conversion, such as the image formation 、 scanning and so on. the typical result behaves blurry 、 distortion 、 having noise etc. in order to denoise and improve the image quality, image restoration has an important meaning

    目前，數字圖像處理已經成為信息處理科學的一個重要部分，在眾多的圖像處理應用中，尤其是在天文學、醫學、軍事應用領域都對圖像數據的真實性有較高的要求，即使日常的圖像通信也要求獲得盡可能高的質量，但在各類圖像處理系統中，由於圖像的傳送和轉換，如成像、復制、掃描、傳輸、顯示等，不可避免的要造成圖像的降質，典型的表現為圖像模糊、失真、有噪聲等，為了去除噪聲、改善圖像質量，圖像恢復具有非常重要的意義;除此之外，很多情況下常常要求及時甚至實時地得到真實的圖像數據。
