Reconstruction and Visualization of Anatomical Structures in Insects
As a first approach we applied state-of-the-art segmentation tools like the seed-based watershed algorithm to segment detailed anatomical structures of the Hawaiian planthoppers Oliarus from high-resolution synchroton µCT images. A result can be seen in Fig. 1. The approach worked well but required a lot of user-interaction. A goal of this project will be to develop interactive segmentation tools that allows the biological expert to quickly segment anatomical structures. Furthermore, we aim at developing visualization tools that allow biologists to qualitatively as well as quantitatively compare anatomical structures of different species.
In a recent publication [Hoch, Wessel et al., 2014] we showed that high-resolution synchrotron µCT is well-suited to investigate even fine details of the lateral abdominal sensory and secretory organs (LASSO) of the taxon Bennini both in nymphs (Fig. 2) and adults.
