Figure 3

Volume paint selection of neural structures from a confocal volume. A: The visualization of certain neural structures (top) and the camera setup (bottom). B: A user paints on the viewport. The stroke (green) is projected back into the volume to define the seed generation region. C: The user paints on the viewport to define the diffusion region. The stroke (red) is projected similarly and the seeds generated in B grow to either the structural boundaries or the boundary defined by the red stroke. D: The intended neural structure is extracted.
