Facial features’ localization using a morphological operation

Facial features’ localization is an important part of various applications such as face recognition, facial expression detection and human computer
interaction. It plays an essential role in human face analysis especially in
searching for facial features (mouth, nose and eyes) when the face region is included within the image. Most of these applications require the face and facial
feature detection algorithms. In this paper, a new method is proposed to locate
facial features. A morphological operation is used to locate the pupils of the
eyes and estimate the mouth position according to them. The boundaries of the
allocated features are computed as a result when the features are allocated. The
results obtained from this work indicate that the algorithm has been very successful in recognising different types of facial expressions.
