Abstract:

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 three-dimensional 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.

Key words: remote sensing image denoising, 3D block matching method, adaptive median filtering, mixed noise
