the risks of fire and explosion in oil and gas industry need to be managed. the objectives of the present study were to assess the risk of fire and explosion in iso-max unit of tehran oil refinery using dow’s fire and explosion index and to study the influences of the controlling methods. the latest version of dow fire and explosion index guideline was applied to calculate the fire and explosio...

A previous study showed that the initial ocular following responses elicited by sudden motion of a large random-dot pattern were only modestly attenuated when that whole pattern was shifted out of the plane of fixation by altering its horizontal binocular disparity, but the same disparity applied to a restricted region of the dots had a much more powerful effect [Vision Research 41 (2001) 3371]...

We performed the first large-scale (n = 501), quantitative study of horizontal disparity tuning in the middle temporal (MT) visual area of alert, fixating macaque monkeys. Using random-dot stereograms, we quantified the direction tuning, speed tuning, horizontal disparity tuning, and size tuning of each neuron. The vast majority (93%) of MT neurons were significantly tuned for horizontal dispar...

In this paper, a hierarchical genetic algorithm for disparity estimation is presented. The goal, to estimate reliable disparity fields with low computational cost, is reached using a hierarchical genetic matching procedure. Firstly, each hierarchical image of the stereo pair is divided into sets of feature points and non-feature points. The image morphological gradient for feature points and th...

We propose a system to perform disparity estimation for a pair of stereo images using object-based global constraints. EEective global constraints are crucial to accurate disparity estimation under the presence of partially occluded areas, illumination diierences, and object deformation. In our method, object contours are rst extracted and their disparities are estimated using a robust tree mat...

This paper proposes a parallel matching algorithm for feature-based stereo vision. Features are zero-crossing (ZC) points detected with various sizes of Laplacian-Gaussian filters. In order to obtain candidate intervals of disparity, the disparity histogram is computed all over the image. The image is, then, divided into small areas and the disparity histogram in each local area is computed wit...

The 3D reconstruction algorithm in a stereo image pair for realizing mutual occlusion and interactions between the real and virtual world in an image synthesis is proposed. A two-stage algorithm, consisting of disparity estimation and regularization is used to locate a smooth and precise disparity vector. The hierarchical disparity estimation technique increases the efficiency and reliability o...

The ability to detect surfaces was studied in a multiple-cue condition in which binocular disparity and motion parallax could specify independent depth configurations. On trials on which binocular disparity and motion parallax were presented together, either binocular disparity or motion parallax could indicate a surface in one of two intervals; in the other interval, both sources indicated a v...

MARK C. PAULK Software Engineering Institute he Capability Maturity Model T Model for Software, developed by the Software Engineering Institute, and the ISO 9000 series of standards, developed by the International Organization for Standardization, have the common concern of quality and process management. The two are driven by similar issues and are intuitively correlated, but they differ in th...

In this paper, we describe the LIA system proposed for the MediaEval 2013 Crowdsourcing for Social Multimedia task. The aim is to associate an accurate label to an image among multiple noisy labels collected from a crowdsourcing platform. In particular, the task participants have to predict two types of binary labels for each considered image. The first one mentions that an image is truly fashi...
