Size- and Shape-Related Principal Component Analysis

The separation of morphometric variation into a component related to size and other components associated with shape is of considerable interest and has generated much discussion in the literature. One class of approaches to achieving this separation is based on principal component analysis. A new t...

Description
Summary:The separation of morphometric variation into a component related to size and other components associated with shape is of considerable interest and has generated much discussion in the literature. One class of approaches to achieving this separation is based on principal component analysis. A new technique is proposed within this class, which overcomes some of the disadvantages of existing approaches.
