Standard FCM algorithm takes the pixel gray-scale information into account only, while ignoring the spatial location of pixels, so the standard FCM algorithm is sensitive to noise. This paper present a pavement image segmentation algorithm based on FCM algorithm using neighborhood information. The presented algorithm introduces neighborhood information into membership function to improve the st...

background: noise is one of the most important harmful agents in work environment. noise pollution in oil refinery industries is related to workers' health. this study aimed to determine the overall noise pollution of an oil refinery operation and its frequency analysis to determine the control plan for a vent noise in these industries. methods: this experimental study performed in control unit...

In this paper, a novel and effective method for removal of blotches and impulse noises in corrupted color images is discussed. The new method consists of two phases. The first phase is a noise detection phase where a nonlinear decision based algorithm is used to detect impulse noise pixels. The second is a noise filtering phase where a new algorithm based on performing vector median first in RG...

The processing of sound changes and involuntary attention to them has been widely studied with event-related brain potentials (ERPs). Recently, functional magnetic resonance imaging (fMRI) has been applied to determine the neural mechanisms of involuntary attention and the sources of the corresponding ERP components. The gradient-coil switching noise from the MRI scanner, however, is a challeng...

background and aim : the quick speech in noise (q-sin) test have been designed to evalu­ate individuals’ ability to recognize speech in noise. this study established to evaluate the test-retest reliability and equivalency of the five test lists of the persian q-sin test in subjects with sensory hearing loss (shl) and normal hearing individuals. methods : this cross-sectional study was per­forme...

This a descriptive with quantitative methods. sample used total sampling, which means that all members...

Sound as a non-visual component of landscape, has a significant impact on individuals perception of space. Because unlike the landscape that seeing and looking is totally an optional action, soundscape regardless of people comes to be heard and understood. Lack of attention to quality of emitted sounds in the environment may leads to problems such as noise pollution, lack of concentration, nois...
