基于像素同龄组和相邻组的绝缘子去噪方法

摘要

针对红外图像带有脉冲噪声和高斯噪声的特点,提出了一种新的去噪方法.首先根据像素同龄组所含的个数来确定脉冲噪声和信号区域,然后利用像素相邻组判断目标边缘,在保持边缘和有用信号区域不变的同时,利用同龄组内的像素平均值对其它像素进行去噪处理.实验表明,该方法在信噪比上比其它方法要优越,并且能较好地保留边缘等细节信息.%A new denoising method was proposed in the paper according to the characteristics of insulator infrared image with impulse noise and gaussian noise First of all,according to the number of peer group of contains pixels, this paper determined impulse noise and signal areas,and then judged the target edge using neighbor groups. The denosing method uses the average of its peer group members instead of the pixel, and keeps the useful signal areas and edge areas at the same time. The experiment results show that the method in the signal lo-noise ratio(SNR) has better effect than other methods,and without blurring edges and details.
