Now-a-day's Face detection approach is the best technique to find the identity of any face image. It is a 2-D problem that is used for detection. The information in a face can be efficiently analyzed among the factors like identity, gender, expression, age, race and pose. Generally, face detection technique was designed for single face detection in still images but its scope extended to videos streaming and multiple faces also. As the face images are normally in upright (straight), they can be described by a small set of 2-D characteristics views. Here the images are projected to a feature space or face space to encode the variation between the known face images.
