Statistical shape analysis is a geometrical analysis from a set of shapes in which statistics are measured to describe geometrical properties from similar shapes or different groups, for instance, the difference between male and female Gorilla skull shapes, normal and pathological bone shapes, etc. Some of the important aspects of shape analysis are to obtain a measure of distance between shapes, to estimate average shapes from a (possibly random) sample, also called mean shape, and to estimate shape variability in a sample. One of the main methods used is principal component analysis. Also some procedures for testing the differences of shapes are used, even for small samples. Some applications of Shape Analysis on oncology, on sensor measurement and on geographical profiling are already made

Famous quotes containing the words analysis and/or shape:
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (18381918)
“But her shape is the least of my madness; she has things by which it is more pleasing to die.”
—Propertius Sextus (c. 5016 B.C.)
