摘要:

噪声是通过各种电子通信传输图像时的主要问题。电子通信中最常见的噪声之一是由不稳定电压引起的脉冲噪声。在本文中,已知的图像去噪技术的比较进行了讨论,并使用基于决策的方法已被用于去除脉冲噪声的新技术。这些方法在抑制脉冲噪声的同时,能较好地保留图像细节。首先介绍了这些技术的原理,然后利用MATLAB进行了各种仿真结果分析。大多数先前已知的技术适用于以较小的噪声密度对损坏的图像进行去噪。这里提出了一种新的基于决策的技术,它比已经使用的技术表现出更好的性能。在视觉欣赏的基础上,通过对不同滤波图像的均方误差(MSE)和峰值信噪比(PSNR)进行定量比较。

英文摘要:

Noise is a major issue while transferring images through all kinds of electronic communication. One of the most common noise in electronic communication is an impulse noise which is caused by unstable voltage. In this paper, the comparison of known image denoising techniques is discussed and a new technique using the decision based approach has been used for the removal of impulse noise. All these methods can primarily preserve image details while suppressing impulsive noise. The principle of these techniques is at first introduced and then analysed with various simulation results using MATLAB. Most of the previously known techniques are applicable for the denoising of images corrupted with less noise density. Here a new decision based technique has been presented which shows better performances than those already being used. The comparisons are made based on visual appreciation and further quantitatively by Mean Square error (MSE) and Peak Signal to Noise Ratio (PSNR) of different filtered images..
