We propose a novel human face recognition approach in this paper, based on two-dimensional Gabor filtering and supervised classification. The feature extraction technique proposed in this article uses 2D Gabor filter banks and produces robust 3D face feature vectors. A supervised classifier, using minimum average distances, is developed for these vectors. The recognition process is completed by...

background :soft tissue profile can be widely different in various populations. furthermore, this profile can be also continues to change throughout life. however, there are few studies that quantitatively evaluate the soft tissue profile in iranian population. in order to determine normal reference values of facial parts in our populations, we aimed to measure standards for facial soft tissue ...

Objective To evaluate a "telephone first" approach, in which all patients wanting to see a general practitioner (GP) are asked to speak to a GP on the phone before being given an appointment for a face to face consultation.Design Time series and cross sectional analysis of routine healthcare data, data from national surveys, and primary survey data.Participants 147 general practices adopting th...

In today’s world, importance of biometric studies is increasing day by day. Biometric face recognition study is the most widely used method in the legal environment. Commonly, face image uses in all identification (IDs, driver’s license, passport, etc.). In particularly, to improve the social security of city life, automatic face detection and face recognition systems are needed and there is a ...

There have been sparse reports in literature of avulsion and degloving injuries of individual areas of face like the nose, eyelids, ear and even mandible. Hemi-facial degloving is extremely rare. We present a case of post-assault degloving of the nose, part of forehead with anterior wall of frontal sinus, entire upper and lower eyelids and the cheek. Proper planning and staging of the surgical ...

We show that a PL-realization of a closed connected manifold of dimension n − 1 in R (n ≥ 3) is the boundary of a convex polyhedron if and only if the interior of each (n− 3)-face has a point, which has a neighborhood lying on the boundary of a convex n-dimensional body. This result is derived from a generalization of Van Heijenoort’s theorem on locally convex manifolds to the spherical case. N...

Young (n = 24) and old (n = 24) participants rated 160 faces of young and old individuals taken from the CAL/PAL Face Database (Minear & Park, 2004) with regard to attractiveness, likeability, distinctiveness, goal orientation, energy, mood, and age. Ratings are reported for each face separately. Further analyses showed that the age groups differed in their ratings of young and old faces. On av...

Face recognition (PCA algorithm) based on principal component analysis method is a classic algorithm of digital information face recognition. This paper first analyzes the PCA algorithm and its basic principles. And in view of the shortage that it is affected by its subject facial expression changes and other factors, it designs the improved PCA algorithm, namely adding the image enhancement pr...

In order to establish face recognition system in rehabilitation nursing robots beds and achieve real-time monitor the patient on the bed. We propose a face recognition method based on partial matching Hu moments which apply for rehabilitation nursing robots beds. Firstly we using Haar classifier to detect human faces automatically in dynamic video frames. Secondly we using Otsu threshold method...
