Human Body Shape Modeling and Analysis
Characterizing and understanding the human shape variation
is essential for many applications. Examples include product design,
clothing, and health monitoring. Traditional anthropometry uses simple tools,
like calipers and tape measures, to measure linear distances between
anatomical landmarks. These measurements do not provide a unique description
of the body shape. They are also subject to human errors. With the
development of 3D laser scanning technology, it is now possible to capture
the entire body surface. Thus, a new field, 3D Anthropometry, has emerged.
The first 3D anthropometric survey is the CAESAR (Civilian American and
European Surface Anthropometry Resource) project. About 6000 civilians in the
The goal of this project is to analyze the variability of the human body
shape. We performed statistical shape analysis on the CAESAR database. The main
modes of variation were extracted from a small number of principle
components. Some of them correspond to our intuitive body characteristics
such as height, weight, muscularity, etc.
Analyzing and visualizing these variations form the foundation of many
applications such as designing of clothing, helmets, masks, and other
products that fit the human body better. It may also help build shape priors
that can be used for reconstructing, recognizing, tracking, and animating
human shapes. Shape variations induced by some of the main components
