Body Weight Measurement Using Image Processing Based on Body Surface Area and Elliptical Tube Volume

Body weight is an indicator that shows many things from someones body. There are two ways to measure our body weight, analog and digital depend on body scales that is being used. Traditional body scales are accurate, but also get some weaknesses such as the likelihood of the result being misread by the user. This research is about detecting someones weight through his photograph. Elliptical tube volume and body surface area are two different methods that are used for this research. Both methods assume human body consists of many small size tubes. For elliptical tube volume, human's body weight is measured by applying volume's tube formula. But for body surface area, the human's body weight is measured by applying surface area of a tube. From the results of the study, the elliptical tube volume method's accuracy is 93,271% and body surface area method's accuracy is 92,854%. The elliptical tube volume method is more accurate than the body surface area method.
