摘要
为了减弱遥感影像噪声的影响,提高影像使用价值,提出了一种新的针对遥感影像混合噪声去噪的组合滤波,即基于三维块匹配和自适应中值滤波的去噪方法;此外使用rbio3小波和db20小波替换传统三维块匹配参数,进行两个仿真试验和一个真实遥感图像去噪试验。结果表明:本文方法在去除遥感影像常见的脉冲与高斯噪声方面,效果优于传统滤波方法。
In order to weaken the influence of remote sensing image noise and improve the use value of imagery,a new combined filtering method is proposed for the mixed noise denoising of remote sensing images,namely the denoising method based on threedimensional block matching and adaptive median filtering.The rbio3 wavelet and db20 wavelet replace the traditional three-dimensional block matching parameters.Two simulation experiments and one real remote sensing image denoising experiment are performed.The results show that this method is better than the traditional filtering method in removing the common pulse and Gaussian noise of remote sensing images.
