A space variant neural network based on an autoregressive moving average (ARMA) process is proposed for blind image deconvolution. An extended cost function motivated by human visual perception is developed to simultaneously identify the blur and restore the image degraded by space variant non-causal blur and additive white Gaussian noise (AWGN). Since the blur affects various regions of the im...

Traditional algorithms for suppressing background noise in speech signals can add annoying artefacts to the resulting denoised signal. In applications requiring better than toll quality, it is desirable that noise suppression should not add any audible artefacts. This paper describes a method that is effective for narrowband and applies these methods to wideband signals. The method presented us...

Abstract In hydraulic equipment, tip clearance may result in a leakage vortex known as (TLV), which reduces the machinery’s energy efficiency. order to lessen damage brought on by clearance, this research sets angle, location, spacing, and depth of grooves significant criteria. The orthogonal approach is used design hydrofoil’s grooves. Numerous simulations are carried out using SST k-turbulenc...

This paper proposes a new switching median filter for suppressing multi-pixel impulse noise in X-ray images. A is understood as set of several neighboring pixels, the intensity each significantly exceeds background intensity. Multi-pixel can occur, example, due to blooming effect, reason being limited value pixel saturation capacity. article defines thresholds increment relative eight immediate...

In this paper a novel class of noise attenuating and edge enhancing filters for color image processing is introduced and analyzed. The proposed adaptive filter design is minimizing the cumulative dissimilarity measure of a cluster of pixels belonging to the sliding filtering window and outputs the centrally located pixel. The proposed filter is computationally efficient, easy to implement and v...

In this paper, we proposed a new adaptive median filter for image denoising. In our method, two thresholds have been involved for detecting noises in variable-sized windows. The median filter and the mean filter are combined for changing the value of the corrupted pixels. The filter can preserve the fine details of image while suppressing the impulsive-type noise. The results of the experiments...

This paper presents a novel filtering framework capable of processing cDNA microarray images. The proposed two-component adaptive vector filters integrate well-known concepts from the areas of fuzzy set theory, nonlinear filtering, multidimensional scaling and robust order-statistics. By appropriately setting the weighting coefficients in a generalized framework, the method is capable of removi...

Refrigerant compressors can be a primary noise source in residential air conditioning and heat pump systems. When evaluating the contribution of a compressor to the total noise, it is necessary to consider how the compressor couples to the condensing unit. Compressors typically couple to the condensing unit via three different types of noise paths. First, the compressor couples structurally to ...
