What are machine learning models/image processing techniques?

Summary
BodyScan uses machine learning models and image processing techniques to estimate and then return a User’s body composition and various body circumferences.

Machine learning is a branch of artificial intelligence (AI) and computer science which focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy. Machine learning algorithms are typically created using frameworks that accelerate solution development. Algorithms build a model based on sample data, known as training data, in order to make predictions or decisions without being explicitly programmed to do so.  

Image processing is the process of transforming an image into a digital form and performing certain operations to get useful information from it. It is one of the fastest-growing technologies today, with its use in various business sectors.
