摘要 针对多普勒天气雷达图像中中气旋的特征,提出了一种基于数学形态学的自动识别算法。为了能有效识别出组成中气旋的一对极值区域,借鉴浸水模拟分水岭算法的思想,构造了一种结合区域属性约束的改进浸水模拟算法用于中气旋识别。新方法比较符合气象人员的视觉经验,充分利用中气旋的图像特征以满足特定的识别需求。对实测数据的识别结果表明了该方法的有效性。 A new recognition algorithm based on mathematical morphology is presented for the characteristics of mesocyclone in Doppler radar images.In order to effectively identify the extreme regions in a mesocyclone,a new flooding algorithm is proposed based on the regional attributes bound.The proposed algorithm well accords with the visual experience of professionals.Experiments demonstrate the effectiveness of the new algorithm.
