WebApr 10, 2024 · Traditionally, there are two commonly used individual tree segmentation methods: the CHM-based segmentation methods and the cluster-based graph cut methods . CHM-based segmentation method can quickly segment tree point clouds, but the CHM transformation can result in the loss of most crucial geometric and spatial context … Web1.1.1 Region Based Segmentation A region-based method usually proceeds as follows: The image is partitioned into connected regions by grouping neighboring pixels of similarintensity levels. Adjacent regions are then merged under some criterion such as homogeneity or sharpnessof region boundaries.
