A real-time display methods for large-scale human body data

초록

As the importance of big-data processing has increased, a considerable amount of research has been done in several areas. We focused on developing methods and applications of multimedia big-data manipulation in the medical field, particularly display methods for large-scale human body data. We proposed context-aware detail level selection and block-based volume rendering methods to generate high-quality images in real-time by handling the huge amount of data efficiently, even in stand-alone computers. We also proposed Gaussian distribution sampling and morphological erosion that produce good quality images even when we used roughly segmented volume data. An entire rendering system is implemented to make the best use of a graphics processing unit’s (GPU) capabilities for real-time processing. To verify the effectiveness of these algorithms, we developed two medical applications called virtual endoscopy and virtual dissection. The experimental results shows that our method efficiently provides high-quality medical visualization even when we use a large medical volume dataset. © 2016 Springer Science+Business Media New York
