Abstract: Methods and apparatus for determining information about an object are provided. An image of an object is acquired, dimensional information about the object are estimated based on the image data, and weight information is determined about the object using the estimated dimensional information. The image may be displayed with the object dimensional information and/or with the object weight information. The image may be stored and/or shared with the object dimensional and weight information. In addition, other information may be entered by a user and stored and/or shared with the image. A medical condition of a person may be determined by acquiring an image of the person, estimating height and weight information for the person based on image data, and determining a medical condition using the estimated height and weight information.
