Improved marked-based watershed algorithm for segmentation of high spatial resolution remote sensing imagery
改进的标记分水岭遥感影像分割方法*

This paper proposed an improved marked-based watershed image segmentation method based on Meyer's algorithm.The method extracted the markers automatically according to the gradient distribution.In the flooding process,processed the unmarked pixels sequentially with an ascending order according to the gradient value,and used the forward order priority queue and reverse order priority queue to record the current processed pixel.Experiment results show the proposed algorithm performs well with high efficiency ...
