Abstract
A method and system to digitally measure area/volume and body surface area of a person and estimate corresponding density and composition as related to a fixed reference frame. This Digital Image Volume Assessment System (DIVAS™) has many desirable features, such as computerized accuracy, precision, convenience, minimal operator expertise and subject compliance is required, and it is economical and expeditious.
Claims20
A method of digitally ascertaining one or more biometric parameters of a subject, comprising the steps of:
- providing a backdrop of contrasting color to that of the subject within a standardized and controlled clearly-defined reference frame;
- presenting the subject in at least a partial covering having a color which contrasts with the subject and with said contrasting backdrop within said standardized and controlled reference frame;
- orienting the subject in a first predetermined position relative to a digital camera so that the subject is in said standardized and controlled reference frame and is disposed between said digital camera and said backdrop;
- taking a first digital photograph of the subject in said first predetermined position;
- counting from said first digital photograph and then subtracting individual pixels from a reference value of total available pixels within said standardized and controlled demonstrative reference frame;
- orienting the subject in a second predetermined position relative to and at a predetermined distance from a digital camera so that the subject is in said standardized and controlled demonstrative reference frame and is disposed between said digital camera and said backdrop;
- taking a second digital photograph of the subject in said first predetermined position;
- counting from said second digital photograph and then subtracting individual pixels from a reference value of total available pixels within said standardized and controlled demonstrative reference frame;
- and
- determining from said counting and subtracting steps one or more biometric parameters of the subject.

A system for digitally ascertaining one or more biometric parameters of a subject, comprising:
- first means for providing a homogeneous colored backdrop within a standardized and controlled demonstrative reference frame;
- second means for presenting the subject in at least a partial covering having a color which contrasts with the subject and with said backdrop within said standardized and controlled demonstrative reference frame;
- third means for orienting the subject in a first predetermined position relative to and at a predetermined distance from a digital camera so that the subject is in said standardized and controlled demonstrative reference frame and is disposed between said digital camera and said back-lit white backdrop;
- fourth means for taking a first digital photograph of the subject in said first predetermined position;
- fifth means for counting from said first digital photograph and then subtracting individual pixels from a reference value of total available pixels within said standardized and controlled demonstrative reference frame;
- sixth means for orienting the subject in a second predetermined position relative to and at a predetermined distance from a digital camera so that the subject is in said standardized and controlled demonstrative reference frame and is disposed between said digital camera and said backdrop;
- said fourth mean further taking a second digital photograph of the subject in said first predetermined position;
- said sixth means counting from said second digital photograph and then subtracting individual pixels from a reference value of total available pixels within said standardized and controlled demonstrative reference frame;
- and
- seventh means for determining from said counting and subtracting steps one or more biometric parameters of the subject.
