Morphometry is defined as the measurement of the external and perceptible characteristics, i.e., in a first approximation, of the shape or morphology of an object. It includes information related to the object’s appearance as well as to its physical and diachronic constitution (Verrecchia, 2003). Morphometric studies attempt to describe this form or shape through mathematical relationships that allow numerical data, and this can be achieved in different ways. In general, tow main types of analysis can be performed whether they are or they are not based on the study of the contourn. In several instances, the actual contourn is not supposed to be really informative. Instead, elementary Euclidean geometrical measurements or the definition of significant points (landmarks or semi-landmarks), referenced in coordinates systems, are used.
