  1. In recent years, nonlinear methods have attracted more and more attention and there have been some successful cases, such as median filter, mathematical morphology, etc. as a preferred way to inverstigate nonlinear numerical problems, the continued fractions method can effectively express the gradually changing data or abrupt data, so it is meaningful to study image processing by means of the continued fractions theory and algorithms

    近年來在圖像處理領域，利用非線性方法進行圖像處理取得較好效果的有中值濾波、數學形態學等，非線性方法已引起越來越多研究者的重視。作為研究非線性數值問題的首選方法?連分式方法，不僅能反映數據的漸變性，也能反映數據的突變性。鑒于這些原因，本文將連分式插值和逼近引入到數字圖像處理領域，開展了圖像插值、圖像重建等方面的研究。
  2. After introducing the characters of the facial expression, the head frame including facial modeling is discussed in detail first, then we construct the parameterization of the head frame, as well as the transform, shading, li ghting of the facial model. the frame of the eyes and the mouth are mainly introduced. based on the theory of the facial action unit, we propose a simplified muscle movement model, in which the movement of the control points reflects the transform of the action units

    其中重點介紹了嘴巴和眼睛的線框以及臉部線框的局部細分方法；然後介紹了臉部表情運動單元的規則，並且分析了國內外學者提出的各種肌肉運動模型，根據表情製作的需要，提出了一種簡化的肌肉運動模型，即用控制點的位移來反映運動單元的變形，因為控制點的位移比較容易從圖像分析的過程中提取；最後介紹了真實感表情製作中用到的紋理映射演算法，運用au產生表情動畫的方法，並給出了實驗結果。
  3. Second, a parallel adaptive ray - casting algorithm for graphic rendering of cfi is developed. in the computational model of cfi, the line - of - sight integration is difficult to obtain for 3d complicated flow field, because curvilinear grids, multizone curvilinear grids, and other irregular grids that are commonly used in computational fluid dynamics ( cfd ) present interesting challenges, such as the complex shapes of cell regions defined by grid points ; the wide variation in the sizes of cells in different regions of the grid ; and the intersecting or overlapping nature of multi - grids. the parallel adaptive ray - casting algorithm is extremely efficient to solve these problems

    并行自適應光線投射法繼承了光線投射法適合於任何形式網格的優點；光線與計算網格的交點自適應地反映了原來網格點物理量的分佈，能夠與數值計算的精度保持一致；圖像平面的自適應演算法使我們不必從每一個像素發出射線，既提高了光線投射法的計算效率，同時又保證重采樣后激波這樣的高頻信息不會損失；將并行處理技術引入計算光學流動圖像生成過程，解決了大規模數值模擬結果的處理對計算速度和內存容量的需求。
  4. It is appropriate commonly that the resolution of ccd sensor imaging is 1. 8 times of the pixel dimension, in the mean while the mtf decreases 11 %, because the mtf is bigger, the other parts are easier to be made and the image shows the characterization of the object well. 2

    一般情況下取ccd探測器的目標影像分辨力是其像元尺寸的1 . 8倍較為適中，因為這時的mtf數值較大對系統的其它環節的指標壓力較小，且圖像較好地反映了目標圖形的特徵，此時其光學調制度傳遞函數mtf下降了11 。
