Image of the Day
The images that appear in the "Image of the Day" are selected for the freshness of their views on Brain Mapping, their esthetic appeal, their quirkiness, or someimes just to prod you into thinking about the field and its context. Their appearance here is not an endorsement of their subject matter.

Visual Complexity
As an undergraduate at UC Davis, Patrick Yau had the opportunity to work at the Visualization and Graphics Research Group in the Institute for Data Analysis and Visualization (IDAV). He was under the guidance of Professor Bernd Hamann and Dr. Lars Linsen when he and his colleagues developed the project "Brain Mapping via Hierarchical Isosurface Segmentation Based on Discrete Curvature".The idea of the project is to look into the surface of two brains and identify the similarities between then. They focused in particular on the curvature of the brains (folds and bumps). Yau worked on data preprocessing and the automated brain mapping algorithm. He wrote a procedure that automatically identifies the front, side and the top for two brains using Principal Component Analysis (PCA), and he also wrote a procedure that constructs a topology graph based on the curvature of a brain. The two images shown here reveal different representations of the same brain: as points and as a topology graph. |
