In this paper, we present an implementation of the PARIGI method that addresses the problem of the restoration of images affected by impulse noise or by a mixture of Gaussian and impulse noise. The method relies on a patch-based approach, which requires careful choices for both the distance between patches and for the statistical estimator of the original patch. Experiments are performed in the...

Background: The purpose of this study was to calculate and compare the specificity and sensitivity of impulse oscillometry (IOS) as a new technique in the detection of airways dysfunction by means of a simple pulmonary function test in chemical warfare injured cases suffering from respiratory diseases. Methods: The study was performed prospectively in 100 patients, who complained of dyspnea as ...

Eliminating of impulse noise from images without losing their features is an important requirement in image processing applications. The standard median filter is a good nonlinear filter for eliminating impulse noise; however, it fails to preserve the image details when the window size is made larger. In this paper, three nonlinear filtering schemes, based on Rank-Ordered Logarithmic Difference...

This paper proposes the median-type filters with an impulse noise detector using the decision tree and the particle swarm optimization, for the recovery of the corrupted gray-level images by impulse noises. It first utilizes an impulse noise detector to determine whether a pixel is corrupted or not. If yes, the filtering component in this method is triggered to filter it. Otherwise, the pixel i...

Online stores spring up everywhere and their store display changes more agilely than the brick-andmortar ones. The webpage aesthetics in online stores, similar to in-store atmospherics in brick-andmortar stores, are significant to consumer impulse buying, yet has received very limited attention from researchers. This paper reports three empirical studies that examine how webpage aesthetic compo...

This paper presents the Impulse adaptable memory system, which allows applications to make efficient use of cache space and bus bandwidth. Impulse has a configurable memory controller that allows applications to remap data in the memory system. As a result, applications can control how their data is accessed, organized, and cached. We describe the current design of the Impulse architecture, des...

In this paper we proposed an efficient mechanism for removal of impulse noise from the digital images. The proposed filter is Segment based Constructive median (SCM), is integration of a cascaded easy to implement impulse detector and a detail preserving noise filter. In the first phase ,the impulse detector classifies any possible impulsive noise pixels. In the second phase filtering replaces ...

Impulse noise is caused by errors in the data transmission generated in noisy sensors or communication channels, or by errors during the data capture from digital cameras. Noise is usually quantified by the percentage of pixels which are corrupted. Corrupted pixels are either set to the maximum value or have single bits flipped over. In some cases, single pixels are set alternatively to zero or...
