Localized Statistical Shape Models

I have succesfully defended my thesis work: Localized statistical shape models for detection of osteoarthritic changes of the trapezium.

I developed a method to obtain a localized statistical shape model similar to the method proposed by Alcantara. However, this new method has a smooth optimization function and can be applied to much denser models. The image below shows the difference between using principle component analysis (left) and the new method. The red region shows the area effected by a particular mode describing the deterioration of surface as a result of osteoarthritis.
