Overview of our proposed neuron morphology analysis pipeline. Given a surface point cloud as input, we extract the skeleton mesh. The skeleton mesh includes skeleton points with their radii as well as the connection of skeleton points. Then we construct the skeleton graph. Each node in a skeleton graph represents a skeleton point, and edge in the graph represents the connection between skeleton points. Next, we propose a graph analysis method to get length and number of branches of neurons based on the skeleton graph. We also use the skeleton graph for classification task by embedding it into a fixed length vector
