Abstract
Methods and systems are provided for measuring anatomical dimensions from a single two-dimensional (2D) digital image. The digital image is taken from the front/anterior view using a mobile, handheld communication device. The linear measurements are used to estimate the body volume of the individual. Total body density is calculated from estimated body volume and body weight. Body composition (fat mass and fat-free mass) of the individual is derived from density using known mathematical conversion formulas. A method for estimating body composition analysis is provided.
Claims20
A method of deriving body composition of an individual, the method comprising:
- obtaining an image of the individual;
- measuring a cross-sectional diameter (linear distance) at a plurality of anatomical landmarks on the image of the individual;
- estimating a body volume of the individual;
- and
- estimating a body composition of the individual using the estimated body volume.
A system of deriving body composition of an individual, the system comprising:
- an image capture device;
- and
- a computing device configured to receive images of the individual, analyze the linear distance related to anatomical landmarks from the digital images to obtain linear measurements, estimate the body volume of the individual using the linear measurements, and estimate body composition of the individual based at least in part upon the estimated volume.
A system comprising:
- an image capture apparatus to receive an image of an individual;
- a landmark identifier module;
- a measurement module to estimate the body volume of the individual by measuring the cross-sectional diameter (linear distance) at a plurality of anatomical landmarks;
- and
- a body composition assessment module to estimate the body composition of the individual based in part upon the estimated volume.
