暴雨分级卫星云图模型和模式识别
SATELLITE CLOUD IMAGE MODEL OF CATEGORICAL HEAVY-RAIN AND PATTERN RECOGNITION
-
摘要: 详细分析了1982年到1998年各种暴雨过程的卫星云图,归纳出了暴雨分级卫星云图模型。对卫星云图模型进行了图象处理,提取出了卫星云图模型的纹理、结构、灰度等特征,用统计与句法相结合的方法进行模式识别,效果良好。Abstract: Satellite image of heavy-rain cases from 1982 to 1998 have been analysed in detail. Categorical heavy-rain model have been induced. After satellite images are processed,the features of vein,greyness,structure have been abstracted. Statistics and syntax methods have been used on pattern recognition and satisfactory result have been obtained.
