Project Description
Statistical shape analysis develops methods for the geometric study of objects. A common way to represent shapes for a group of images is the geometric transformation between each individual and the mean image. Analyzing diffeomorphic shape changes can be linked to disease processes and changes in cognitive and behavioral measures.One challenge of shape variability quantification is 'the curse of dimensionality', for instance, the transformation grid 128x128x128 as a shape descriptor for a 3D brain image. This makes the inference procedure computationally complicate and time-consuming. An efficient method needs to be developed to handle this complex dataset.
