Abstract
Apparatus for determining height, width, weight or body mass index (BMI) of a subject or distance along an object. For BMI, the apparatus includes a digital camera; an application; a processing unit for storing the vertical and horizontal dimensions of known substantially rectangular reference objects. A user interface prompts and receives the type of reference object held by the user or its dimensions. For each of the vertical and horizontal dimensions, a magnitude in pixels and in distance of the reference object to form a ratio and a pixel magnitude of the vertical and horizontal dimensions of the subject in the image(s), is used to derive an estimated height and width of the subject from the pixel magnitude of the vertical and horizontal dimensions of the subject in the image(s). In some embodiments, the number of pixels occupied by the subject in the image(s) is used with a look-up table.
