Michael A. Wirth, of GuelphComputing and Information ScienceImage Processing Group 2004 Shape Analysis & Measurement2 Shape Analysis & Measurement The extraction of quantitative feature information from images is the obj e c t i v e o f image Analysis . The objective may be: Shape quantification count the number of structures characterize the Shape of structures3 Shape Measures The most common object measurements made are those that describe Shape . Shape measurementsare physical dimensional measures that characterize the appearance of an object. The goal is to use the fewest necessary measures to characterize an object adequately so that it may be unambiguously Measures The performance of any Shape measurements depends on the quality of the original image and how well objects are pre-processed.
