  1. Among them the gray level co - occurrence matrix ( glcm ) and gray gradient co - occurrence matrix ( ggcm ) methods, which attributed to the statistic textural analysis scheme were then chosen to extract the textural features of five kind areas on satellite images. in the second part the principle of classification and bp neural network were introduced. combined with textural features, the improved bp neural network successfully performed on the classification of the satellite images

    論文的第一部分介紹了進行紋理特徵研究的一些典型的方法,利用其中的基於統計的紋理分析法中的灰度共生矩陣以及灰度一梯度共生矩陣法,分析了衛星雲圖上五類區域的紋理特性;第二部分主要介紹了遙感圖像分類原理以及神經網路中的bp演算法,在對演算法原理進行深入理解的基礎上,把紋理特徵與神經網路進行組合,實現對衛星雲圖進行分類分析;第三部分內容是在前面圖像分類結果的基礎上,對序列圖像用相關匹配法進行運動分析,反演雲跡風風場。

  3. This dissertation deals with the content - based image retrieval ( cbir ) theory and technique ; some new features and tools for more concisely and discriminatingly charactering the content of an image are proposed, such as region - based color histogram, grey - primitive co - occurrence matrix, ratio of centripetal moment, ratio of eccentric moment and ratio of inertial moment. a new modified genetic algorithm is also described in this dissertation, which can upgrade the performance of standard genetic algorithm ( sga ) while used in image segmentation

    本文以圖像數據庫檢索為主線,討論了基於視覺內容的圖像檢索方法,提出包括基於區域顏色直方圖、灰度?基元共生矩陣及向心矩比、偏心矩比、慣性矩比的特徵描述方式;對遺傳演算法存在的早熟、收斂到最優解慢等問題提出了解決方法,並將改進遺傳演算法應用到圖像分割中,編制了相應程序。
