As the world becomes more and more complex and so does the health problems faced by the individuals living on this Earth. Many of the health problems are hard to identify and explain. This is especially true with adolescents who are not able to speak at their early age of life and are not able to express the pain felt. There are also conditions with certain people who suffer from paralyses, strobe or any other similar type of problems where in a person is not able to express the intensity of pain or the kind of pain associated problems faced. With such scenarios there arises a need to develop a system which is capable of recognizing the pain expression using facial features. Once the system is developed, the problems faced by the different kinds of people mentioned above will be solved and a proper treatment plan can be offered to the individual, thus reducing suffering and the money spent. This paper explores the advanced methods and techniques used to develop such a system.
