This study aimed to develop a clinical test of face perception which is applicable to a wide range of patients and can capture normal variability. The Caledonian face test utilises synthetic faces which combine simplicity with sufficient realism to permit individual identification. Face discrimination thresholds (i.e. minimum difference between faces required for accurate discrimination) were d...

Keywords: Face recognition Fisher linear discriminant analysis (FLDA) Single training image per person Singular value decomposition (SVD) a b s t r a c t Fisher linear discriminant analysis (FLDA) has been widely used for feature extraction in face recognition. However, it cannot be used when each object has only one training sample because the intra-class variations cannot be statistically mea...

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 ...

Channelized reservoirs often show multi-scale architectures such as large-scale channel belts, middle-scale single channels and small-scale channel infill facies. These architectural elements are defined between bounding surfaces. Along these hierarchical bounding surfaces, thin shale drapes may be present as flow barriers that compartmentalize the reservoirs. Since the distribution of shale dr...

[1] Clay-rich mass transport deposits (MTDs) in the Ursa Basin, Gulf of Mexico, record failures that mobilized along extensional failure planes and transformed into long runout flows. Failure proceeded retrogressively: scarp formation unloaded adjacent sediment causing extensional failure that drove successive scarp formation updip. This model is developed from three-dimensional seismic reflect...

Face detection and recognition is a vibrant area of biometrics with active research and commercial efforts over the last 20 years. The task of face detection is to search faces in images, reporting their positions by a bounding box. Recent studies [19, 31] have shown that face detection has already been a state-of-the-art technology in both accuracy and speed. However, face detection is not suf...

We present the first purely event-based approach for face detection using an ATIS, a neuromorphic camera. We look for pairs of blinking eyes by comparing local activity across the input frame to a predefined range, which is defined by the number of events per second in a specific location. If within range, the signal is checked for additional constraints such as duration, synchronicity and dist...

The purpose of this paper is control of simply supported flexible core sandwich beam's linear vibration equipped with piezoelectric patches under different loads. The effects of external forces imposed on sandwich beam can be reached to a minimum value by designing an appropriate controller and control the beam's vibration. Three-layer sandwich beam theory is used for analytical modeling of san...

Face detection/recognition applications involve ill-defined concepts (such as 'face' or 'person') that cannot be specified a priori in terms of a small set of features. This implies the need for learning unknown class decision boundaries from data (i.e., images with known class labels). This task is a special case of a generic problem of predictive classification or pattern recognition, where t...
