Diagram of topological analysis. a The root skeleton (blue line) extracted based on the binary image. The endpoints and crossing points are indicated by blue and green points, respectively. b The topological analysis of a primary root (PR) segment includes the skeleton of root segments (white), branching points (red) and two endpoints (green), i.e. the highest endpoint E h and the lowest endpoint E l . c The root skeleton (blue line) extracted based on the binary image and branching points (red). The digits indicate the root order [0 for PR and 1 for the first-order lateral roots (LRs)]. d The root skeleton (blue line) extracted based on the binary image and straightened PR skeleton (red line)
