| 1 Introduction This paper presents a method to construct the average for 2D shape outlines (curves) using their intrinsic properties. A computational framework for constructing an average curve and for characterizing the deviations from the average has a wide variety of applications in medical imaging. For example, in comparing the anatomy of a sample structure to a population of similar structures, the average curve represents the average anatomy. This can be used for measuring differences in anatomy between diseased/healthy, male/female populations, and across a range of ages. Correlating "abnormal" deviations from the average anatomy with diseased states can potentially lead to diagnostic measures and is another important application of this framework. The current clinical language for describing "abnormal" shape is limited to a simple set of measurements in the form of length, areas, volumes, etc. A number of recent approaches have jointly led to the emergence of "computational n... | |||||||||||||||
