Uncertainty Visualization of Projections of Organ Meshes
In many cases, in medical visualization, projections or unfolding of organs are employed for various purposes. However, all projections or unfolding methods come with severe distortions, which are a significant source of uncertainties in the resulting representations. In this project, we would like to investigate different methods of projections (with a focus on geographical-inspired projections) that can be employed for the unfolding of organ meshes. Also, we would like to investigate, visualize and evaluate the magnitude of distortion-induced uncertainty of these projections.
This project is meant to be carried on as a Bachelor or Master thesis, by one student. Depending on whether it is a Bachelor or Master Thesis, the tasks will be tuned.
1) Literature study on projection methods, on their inherent distortions and on uncertainty visualization.
2) Select and implement several projections methods.
3) Calculate, visualize and evaluate the distortion-induced uncertainty of the selected projections.
4) Apply to different organ meshes and evaluate.
- Medical Visualization.
- Knowledge of English language (source code comments and final report should be in English).
- Programming experience (we can discuss implementation possibilities and decide on the best possible option). Knowledge of C++ and Qt is advantageous, but not necessary.
