Statistical shape analysis is a tool that allows to quantify the shape variability of a population of shapes. Traditional
tools to perform statistical shape analysis compute variations that reflect both shape and posture changes
simultaneously. In many applications, such as ergonomic design applications, we are only interested in shape variations. With traditional tools, it is not straightforward to separate shape and posture variations. To overcome this problem, we propose an approach to perform statistical shape analysis in a posture-invariant way. The approach
is based on a local representation that is obtained using the Laplace operator.
