Vision based fire detection has many advantages over traditional methods. In vision based fire detection approaches, it is required that systems must have enough robustness and be insensitive to environment. We mainly take advantage of mixture Gaussian model and frame difference techniques to adaptively extract a background image from image sequences captured by ordinary color cameras. These te...

this research is about the comparison between orthodox mysticism and kubrawiyid sufism on the concept of vision, both of which have common origin. the eastern orthodoxy has esoteric and spiritual epigrams more than other christian sects, and considering geographical and political conditions, has close relationship with the east, specifically islamic world. an important issue of semitic religion...

An interesting feature of the Davies-Unruh effect is that a uniformly accelerated observer sees an isotropic thermal spectrum of particles even though there is a preferred direction in this context, determined by the direction of the acceleration g. We investigate the thermal fluctuations in the Unruh bath by studying the Brownian motion of particles in the bath, especially as regards to isotro...

7th International Conference on Energy Minimization Methods in Computer Vision and Pattern Recognition, Bonn, Germany, August 24-27, 2009 Medical image segmentation appears to be governed by the global intensity level and should be robust to local intensity fluctuation. We develop an efficient spectral graph method which seeks the best segmentation on a stack of gamma transformed versions of th...

Abstract The operational meaning of spacetime fluctuations is discussed. Classical spacetime geometry can be viewed as encoding the relations between the motions of test particles in the geometry. By analogy, quantum fluctuations of spacetime geometry can be interpreted in terms of the fluctuations of these motions. Thus one can give meaning to spacetime fluctuations in terms of observables whi...

purpose: to evaluate the effect of successful surgical alignment on improvement of binocular vision in adults with childhood strabismus methods: in a prospective interventional study, consecutive patients with childhood-onset, comitant, horizontal and constant strabismus who had successful postoperative alignment were enrolled. preoperative and postoperative binocular vision testing was perform...

Most conventional image processors consider little the influence of human vision psychology. Weber’s Law in psychology and psychophysics claims that human’s perception and response to the intensity fluctuation of visual signals are weighted by the background stimulus , instead of being plainly uniform. This paper attempts to integrate this well known perceptual law into the classical total vari...

To acquire images of dynamic scenes from multiple points of view simultaneously, the acquisition time of vision sensors should be synchronized. In this paper, an illumination-based synchronization derived from the phase-locked loop (PLL) mechanism based on the signal normalization method is proposed and evaluated. To eliminate the system dependency due to the amplitude fluctuation of the refere...

background: this study aimed to identify factors contributing to the creation of intellectual capital in the organization of education. the research method is a descriptive and exploratory factor analysis method. a sample: directors and deputies of the second period secondary education department of tehran province. based on stratified random sampling method and based on a sample of 500 was cal...

In the contemporary society of aesthetic daily life, people not only examine commodities, environment and life with a stricter "aesthetic" vision, but also observe others themselves, so that modern people's attention to appearance is beyond past, which brings series problems value orientation. As middle school students, they are in peak psychological fluctuation relationship between experience ...
