Bookstein F.L. Morphometric Tools for Landmark Data: Geometry and Biology

Cambridge University Press, 1992. - 455 Pages.Morphometrics is the statistical study of biological shape and shape change. Its richest data are landmarks, points, such as the bridge of the nose, that have biological names as well as geometric locations. This book is the first systematic survey of morphometric methods for landmark data.Preliminaries
Landmarks
Distance measures
Shape coordinates
Principal axes of shape change for triangles
Features of shape comparison
Retrospect and prospect.
