Universal De-Noising Framework with a New Impulse Detector Algorithm
نویسنده
چکیده
In this paper, new detection mechanism for universal noise and a universal noise-filtering framework based on the nonlocal means (NL-means) has been proposed. It introduce new statistics ROR for describing the outlyingness of the pixels and propose a new detection mechanism. The proposed approach can be adapted to various models such as salt and pepper impulse noise and randomvalued impulse noise by modifying some parameters in the algorithm. Extensive simulations reveal that the performance of the proposed algorithm is impressive as compared to the previously used median filter.

Adaptive Image De-noising Algorithm in Intersecting Cortical Model
Because the classic intersecting cortical model (ICM) and the traditional image de-noising algorithm exist the deficiencies-the image collection, transmission and conversion are often subjected to impulse noise interference, thus affecting the quality of the image, therefore we improved the framework structure and related parameters of the ICM and proposed the adaptive image de-noising algorith...

In this study, in order to simulate the monthly flow of the Khorramabad River, the time series of this river was decomposed into three levels using the wavelet of Daubechies-3, during the period of 1955-2014. Based on this, it was found that there is a Non-uniform noise that includes two periods of time in this signal, with the October 2008 border which required that the signal be become non-un...

Detection of the weak signature of degradation of the Reactor Coolant Pump (RCP) at early stage gives more time for maintenance reaction, safety decision-making and also provides economic benefits. An integrated and improved method to detect and identify abnormality using continuous wavelet transform based sparse code shrinkage de-noising algorithm is suggested in this work. For RCP roller bear...
متن کاملImage Denoising Based On Fast Noise Estimation Methods and Median Algorithm
Impulse noise detection is a critical issue when removing impulse noise and impulse/Gaussian mixed noise. In this paper, we propose a new detection mechanism for universal noise and a universal noise-filtering framework based on the nonlocal means (NL-means). The operation is carried out in two stages, i.e., detection followed by filtering. For detection, first, we propose the robust outlyingne...
متن کاملDe-Noising SPECT Images from a Typical Collimator Using Wavelet Transform
Introduction: SPECT is a diagnostic imaging technique the main disadvantage of which is the existence of Poisson noise. So far, different methods have been used by scientists to improve SPECT images. The Wavelet Transform is a new method for de-noising which is widely used for noise reduction and quality enhancement of images. The purpose of this paper is evaluation of noise reduction in SPECT ...
