| Abstract: |
| The vein of plants contains the important physical characteristics of plants. The vine and its distribution
are foundation and key to the plants’ classification，recognition and modeling. After removing the petiole and the special
points，which can be used to confirm the region of main vein，are obtained by the Curvature’s parameter function of the
edge. In order to avoid the influence of the bending of the main vein and local illumination uneven on the extraction，
the region of the main vein is partitioned. Using the Hough transform，region growing and Harris corner detection，the
nodes’ distribution of the main vein within the partitioned region are obtained，respectively. Then，gathering the nodes’
distribution of all regions，the nodes’ distributing information of the main vein is obtained. The results show that the
algorithms are capable of accurately extracting the nodes and the nodes’ distribution. |
