Face recognition, means checking for the presence of a face from a database that contains many faces and could be performed using the different features. The face images considered for recognition undergo large variations due to changes in the illumination conditions, viewing direction, facial expression and aging. The face images have similar geometrical features. Hence, it is a challenging ta...

the aim of this study was to examine whether formal and informal social activities are associated with a lower risk of depression. besides, we investigated which type of social activities may protect against late-life depression by gender using data from a population-based study of older korean adults.data for analysis were drawn from the 2010 korean longitudinal study of aging. study sample in...

In this paper, we summarize the most used methods for face recognition, including advantages and drawbacks of each system that has been developed until now. Also, we describe the future research lines and discuss the direction of face recognition. This survey is relevant for our research, as we are encouraged to develop a novel face recognition system as part of our future work.

Successful interactions between people are dependent on rapid recognition of social cues. We investigated whether head direction--a powerful social signal--is processed in the absence of conscious awareness. We used continuous flash interocular suppression to render stimuli invisible and compared the reaction time for face detection when faces were turned towards the viewer and turned slightly ...

Important social information can be gathered from the direction of another person's gaze, such as their intentions and aspects of the environment that are relevant to those intentions. Previous work has examined the effect of gaze on attention through the gaze-cueing effect: an enhancement of performance in detecting targets that appear where another person is looking. The present study investi...

A face recognition algorithm based on modular PCA approach is presented in this paper. The proposed algorithm when compared with conventional PCA algorithm has an improved recognition rate for face images with large variations in lighting direction and facial expression. In the proposed technique, the face images are divided into smaller sub-images and the PCA approach is applied to each of the...

To examine the effect of illumination direction on the ability of observers to discriminate between faces, we manipulated the direction of illumination on scanned 3D face models. In order to dissociate the surface reflectance and illumination components of front-view face images, we introduce a symmetry algorithm that can separate the symmetric and asymmetric components of the face in both low ...

This paper addresses listening to three simultaneous talkers by a humanoid with two microphones. In such situations, sound separation and automatic speech recognition (ASR) of the separated speech are difficult, because the number of simultaneous talkers exceeds that of its microphones, the signal-to-noise ratio is quite low (around -3 dB) and noise is not stable due to interfering voices. Huma...

abstractone challenge face political system is implementation national development. there are various models for national development. some countries have relied on import model, but other has emphasis on their indigenous, the purpose of this study is designing intelligence development model in iranian national context. based on the selected theory building methodology, we have theorized intell...
