Algorithm of face angle estimation in the image

The localization of the area of interest in face image to recognition is the key task in face recognition system. The face detection problem is first step before face recognition process. The properties of recognition system depend on the quality of processing images and area of face localization. Many systems are adapted to process the images with frontal type of faces only. We propose the approach to estimate a deviation angle of face from biometric standard in order to expand the range of variety of recognizable face images.
