this paper deals with a globally convergent adaptive and sliding mode control of a cart-pole inverted pendulum for trajectory tracking in the presence of a bounded measurement noise and parameter uncertainty. two kinds of controllers have been used for evaluation of tracking error in presence of a bounded noise; as a result, we want to compare that at what time we can see the convergence of tra...

In this paper a new method, based on subspaces of a cumulant matrix, is proposed for the blind identi"cation of an ARMA system which is driven by white non-Gaussian noise. The relationship between the cumulants and the impulse response is exploited to arrive at a relation between a cumulant matrix and a matrix consisting of impulse responses. This will lead to the formulation of a new algorithm...

This paper addresses the problems of blind channel identification and multichannel equalization for speech dereverberation and noise reduction. The time-domain cross-relation method is not suitable for blind room impulse response identification, due to the near-common zeros of the long impulse responses. We extend the cross-relation method to the short-time Fourier transform (STFT) domain, in w...

Noise is an important factor that degrades the quality of medical images. Impulse noise is a common noise, which is caused by malfunctioning of sensor elements or errors in the transmission of images. In medical images due to presence of white foreground and black background, many pixels have intensities similar to impulse noise and distinction between noisy and regular pixels is difficult. In ...

A digital image is often deteriorated by impulse noise that may occur during processes such as transmission. An impulse noise converts the pixel data in the image into black (0) or white (255) values at a random frequency and is also called salt-and-pepper noise. In this paper, we identify the details of pixels that have been damaged by impulse noise by analyzing the frequency of the noisy imag...

this paper tries to determine efficiency of noise control method using fuzzy logic and based on collected data. from among various methods of noise control in workplace, sex methods (enclosure, installing noise absorber, enclosure and absorber, active, and administrative control, and personal protective equipment) were typically selected based on experts' judgment. for each of selected control ...

Images are often corrupted by impulse noise in the procedures of image acquisition and transmission. Impulse noise is a category of acoustic noise which includes unwanted sharp sounds like click and pops. To avoid the damage on noise liberated pixels, the switching medium filters are used which consists of impulse detection and noise filtering. In our project, we propose an efficient denoising ...

Framelets have been used successfully in various problems in image processing, including inpainting, impulse noise removal, superresolution image restoration, etc. Segmentation is the process of identifying object outlines within images. There are quite a few efficient algorithms for segmentation that depend on the partial differential equation modeling. In this paper, we apply the framelet-bas...

In this paper, we study the restoration of images corrupted by Gaussian plus impulse noise, and propose a l1–l0 minimization approach where the l1 term is used for impulse denoising and the l0 term is used for a sparse representation over certain unknown dictionary of images patches. The main algorithm contains three phases. The first phase is to identify the outlier candidates which are likely...
