  1. In this thesis, the preprocessing work includes histogram equalization and gray normalization. this preprocessing improves image quality, and eliminates the effects of illumination difference on the images

    本論文在預處理階段通過對灰度直方圖修正、灰度歸一等工作改善了原圖像的質量，使光照不均勻對圖像識別的影響降低。
  2. 2. defining the entropy space of image and entropy difference, the concept of information entropy is applied to image retrieval. some mathematical properties of entropy are studied, and similarity measurement of image entropy and corresponding algorithm is presented. these techniques can reduce the dimensionality of histogram space from n to l ( n > l ), increase the image retrieval efficiency, and improve the capability of image retrieval system

    將信息論中的信息熵概念引入圖象檢索，定義了圖象墑空間、熵差的概念，研究了圖象熵的性質，探討了基於圖象熵的相似性度量方法和實現演算法，該方法可將n維直方圖空間變為1維，提高了圖象檢索的效率，改善了圖象檢索系統的性能。
  3. In the mosaic experiment of cbers - 01, this paper chooses the method of one - track multi - band histogram mosaic plus inter - track histogram mosaic to decrease the color difference of images and improve the quality of images

    鑲嵌試驗中，選擇先單軌道多波段直方圖匹配拼接，再進行軌道間直方圖匹配拼結的方法，最終獲得接邊和色彩匹配基本滿意的全貴州cbers - 01影像鑲嵌圖。
  4. Because of the shortage of traditional unsupervised algorithm, three algorithms are proposed in the paper based on the spatial information of the difference image and the clustering characteristic of 2 - d histogram formed by pixel gray levels and the local average gray levels. the proposed algorithms segment the pixels of

    本文針對典型演算法存在的不足，充分利用差異圖象灰度空間分佈信息和差異圖象灰度-鄰域平均灰度二維直方圖的聚類特性提出了三種非監督變化檢測方法，將差異圖象所有像素分成變化和非變化兩個類別。
  5. The main contents can be listed as follows : 1. after analyzing the properties of the natural illuminating system, a region - based background and natural illumination model is set up using the histogram of image difference and rls filter. on the basis of that model, we propose an adaptive algorithm of judging and updating background image

    基於戶外自然光照系統的特點，建立了基於圖像差分直方圖和遞推最小二乘濾波（ recursiveleastsquarefilter ，簡稱rls濾波器）的局域化背景和光照變化模型，提出了自適應的背景判斷和更新演算法。
  6. The following algorithms are proposed : 1. an algorithm of shot segmentation is proposed. firstly, the data in each frame is quantized in hsv model ; then based on histogram of each frame, the difference of adjacent frames, the difference of cumulate frames and the percentage of the frame difference in a defined window are computed ; furthermore, the adaptive average in a window, the adaptive thresholds and sliding windows are obtained

    具體內容為: 1 .在鏡頭分割中，首先將視頻幀數據在hsv顏色空間下進行量化降維，隨后依據直方圖的統計特性，計算連續幀差值，累加幀差值及窗口幀差比，並以此確定自適應窗口均值、多個動態閾值及滑動窗口進行突變鏡頭和漸變境頭分割。
