遥感影像水体追踪识别提取算法及应用

Extraction Algorithm and Application of Remote Sensing Image Water Tracking and Recognition

针对大尺度区域所有规模以上水体一次性智能化水体提取的问题,提出了水体追踪识别提取算法。这种方法可以追踪图像中所有的连通区域,并对区域进行识别与提取。以花马湖区域的水体为例,使用水体追踪识别算法提取湖泊,能够准确地追踪各种形状的湖泊,与两边扫描法、区域增长法相比,扫描重复率低、精度高。

In order to solve the problem of one-time intelligent water extraction for water bodies above all scales in large-scale areas,The extraction algorithm of water body tracking recognition is proposed.This method can trace all connected areas in the image and identify and extract the region.By taking the water bodies in the Huamahu Lake area,using the water body tracking algorithm to extract the lake,this method can accurately track the lakes of various shapes,and the scanning repetition rate is low and the precision is high compared with the scanning method and the regional growth method.
