Abstract

Face Detection of a Human by a Man-made intelligence has got the attention of many researchers and scientists alike. When a computer or a robot could be made to detect a human’s face through either their in-built cameras or any other optical input devices why not also make those camera device determine the expression of that human too? It has become a possibility with the current rise in technology and various other algorithms. To simply put human face involves various facial muscle movements which constitutes to a collective term called Facial Expression. There are particular areas which can be referred to as Critical Points on face whose disposition in a specific pattern can make an individual’s expression, depending on the type of mood or circumstance he/she’s in. There are 6 basic expressions Happy, Sad, Disgust, Anger, Fear and Surprise. Well this paper focuses on determining these expressions which will be explained in the following parts.
