  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特徵研究的一些典型的方法,利用其中的基於統計的分析法中的灰共生矩陣以及灰共生矩陣法,分析了衛星雲圖上五類區域的特性;第二部分主要介紹了遙感圖像分類原以及神經網路中的bp演算法,在對演算法原進行深入解的基礎上,把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。
  2. In the part of image preprocessing, a segmentation algorithm for fingerprint image based on the information of gradient orientations was programmed. according to the uniformity and partial parallarity of ridges and furrows of fingerprint, a model of gabor filter was established to enhance fingerprint image. since two - dimensional gabor filter could be separated into two one - dimensional filters, the complexity of the algorithm could be reduced efficiently
