摘要：
Data filtering and image segmentation are two crucial steps in individual tree information extraction based on airborne LiDAR data. In this paper, a new image segmentation method was proposed to isolate individual tree and extract tree height and size information of the tree crowns, which is the fusion of marker-controlled watershed segmentation and valley-following segmentation. This method can perform edge detection effectively compared to methods before because a special detection constraint was added into it. A real data test was given to testify its validation.
