An Analysis to Identify the Importance of Visual Face Features and Ranking

A person can remember thousands of faces. The face can be remembered based on their different shape size and color. The difference in facial structure and color makes people different from others and easy to remember. The face is a key feature to identify a person. When somebody interacts with an unknown person they remember them with the highlighted features of their face. However, sometime later memory fades. i.e. when some crime happens, the eye witness looks the criminal for a few seconds. Some of the features of his face are remembered by the eye witness. These features are used by the sketch artist to generate the sketch and help for the identification of the suspect. Sketches contain shape and texture information about the face. Color information lags in the sketches. To identify the importance of color information, we have performed a survey. Eye color and skin color along with the twelve other face features are used in conducting this survey. The 3690 responses from 314 persons are collected and analyzed. This survey helps the research community to identify the importance of facial features and ranking them.
