2012 Summer Project Week:4D shape analysis

• 

  Projects List

• 

  Shape evolution of sub-cortical structures. Color denotes magnitude of velocity.

Key Investigators

• Utah: James Fishbaugh, Marcel Prastawa, Guido Gerig

Objective

We are interested in detecting and quantifying shape changes associated with the progression of Huntington's disease. Preliminary experiments on sub-cortical structures in HD from previous project weeks were intended as a test of our methodology. In order to have an impact moving forward, our tools needs to be robust, easy to use, and available as open-source software. The objective is to improve upon our research code base, leveraging open source libraries.

Approach, Plan

We will consider various software design decisions and begin improving research code.
