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。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
在圖像預處理方面,利用指紋圖像梯度特性進行圖像分割,根據指紋紋線間距均勻且局部平行的特點,建立了用於指紋圖像增強的gabor濾波函數物理模型,並將二維gabor濾波分解為兩次一維濾波,有效降低了演算法的復雜度。
