Skeleton Extraction Algorithm of Plant Lein Based on Watershed

摘要

Plant skeleton is a key geometrical of itself, it can reserve topology and shape information of the object, so it is easy to reconstruct the source form. In this paper, leaf vein skeleton extracting method based on watershed was proposed using images of leaves. Through it the main vein and lateral vein of the leaf are extracted. Then use the morphology method like dilation and erosion to do the final post-processing to the skeleton of the leaf veins to obtain the skeleton of leaf veins, so it can provide the foundation for leaf surface modeling and leaves three-dimensional deformation of the visual modeling in the future.
