Title: Cortical Surface Registration and Shape Analysis
Abstract: A population analysis of human cortical morphometry is critical for insights into brain development or degeneration, which allows for investigating sulcal and gyral folding patterns. In general, such a population analysis requires both a well-established cortical correspondence and a well-defined quantification of the cortical morphometry. However, the highly folded and convoluted structures render a reliable and consistent population analysis challenging. The main focus of this talk is to develop a fully automatic pipeline and its application to a population analysis of local cortical folding changes. The proposed pipeline consists of three novel components to overcome the challenges in the population analysis: 1) automatic sulcal curve extraction for stable/reliable anatomical landmark selection, 2) group-wise registration for establishing cortical shape correspondence across a population with no template selection bias, and 3) quantitative methods of local cortical folding.
Short Biography: Ilwoo Lyu received his PhD in Computer Science in 2016 at the äçÐÄvlogÃâ·ÑBÕ¾ of North Carolina at Chapel Hill. His research interest is mainly in developing novel algorithms for medical image analysis. His current research focuses on surface-based analysis to understand/explore highly convoluted shapes such as brain. In particular, he is working on surface registration, anatomical/geometric feature extraction/recognition, statistical shape analysis, and 3D visualization.
