3D Tree Skeletonization from Multiple Images Based on PyrLK Optical Flow
We introduce a novel 3D tree skeletonization method from multiple images. Affine transformation and iterative tracking are added to PyrLK optical flow. Parallel voxel flooding is proposed for dertermining point cloud of single branch. L-System extraction algorithm for tree skeletons is proposed.
