Impulsive Noise Diminution Using New Adaptive Vector Median Rational Hybrid Filter
نویسندگان
چکیده
To ameliorate the quality of filtering, we studied in this paper, the adaptive approach applied in multichannel images. So, we have proposed an Adaptive Vector Median Rational Hybrid Filter (AVMRHF). This filter is based on Adaptive Vector Median Filters (AVMF) and a Vector Rational Function (VRF). The analysis and experimental results reported in this paper indicate that the proposed filter is able to remove impulsive noise in color images. Also, this new filter (AVMRHF) provides better performances comparing with the classic version VMRHF. Indeed, we note an average percentage of 70% of improvement with regard to the NCD parameter between the new filter and the classic one. Keywords—Vector approach; color image; adaptive Filter; VMRHF filter; impulsive noise.

Median-Rational Hybrid Filters
In this paper we introduce a new class of nonlinear filters called Median-Rational Hybrid Filters (MRHF) based on Rational Functions (RF). The filter output is the result of a rational operation taking into account three sub-functions, such as two FIR or median subfilters and one center weighted median filter (CWMF). The proposed MRHF filters have the inherent property that on smooth areas they...
متن کاملImproved Adaptive Median Filter Algorithm for Removing Impulse Noise from Grayscale Images
Digital image is often degraded by many kinds of noise during the process of acquisition and transmission. To make subsequent processing more convenient, it is necessary to decrease the effect of noise. There are many kinds of noises in image, which mainly include salt and pepper noise and Gaussian noise. This paper focuses on median filters to remove the salt and pepper noise. After summarizin...
متن کاملProgrammable Hardware Implementation for the Median-Rational Hybrid Filters
The Median-Rational Hybrid Filter (MRHF) has been recently introduced [1][2] as a new class of nonlinear filters and successfully applied to image filtering problems. The main characteristics of the MRHF are the good noise attenuation property in smooth areas and the preservation of edges end details. In fact, in changing areas the noise attenuation is traded for a good response to the change. ...

A new code sign implementation of vector median rational hybrid filter based on efficient hardware/software implementation is introduced and applied to colour image filtering problems. This filter is used essentially to remove impulsive and Gaussian noise in colour images. In our design we start by implementing the software solution in system on programmable chip context using NIOS-II softcore ...
متن کاملSalt and Pepper Noise Removal using Pixon-based Segmentation and Adaptive Median Filter
Removing salt and pepper noise is an active research area in image processing. In this paper, a two-phase method is proposed for removing salt and pepper noise while preserving edges and fine details. In the first phase, noise candidate pixels are detected which are likely to be contaminated by noise. In the second phase, only noise candidate pixels are restored using adaptive median filter. In...
