FRAMEWORK FOR COMPARING SEGMENTATION ALGORITHMS
Segmentation Algorithms Mapping Point Clouds
2015/5/21
The notion of a ‘Best’ segmentation does not exist. A segmentation algorithm is chosen based on the features it yields, the properties of the segments (point sets) it generates, and the complexity of ...
