Abstract
Multispectral images are obtained by taking multiple images of the different wave bands of the same target, which provides a more comprehensive and clearer description of the scene. However, in practice, multispectral images are always degraded by various types of noise. In this paper, an image denoising method based on non-local means and bilateral filtering is proposed. The method uses the non-local means algorithm to denoise the image, and then uses the bilateral filter to enhance it. The proposed method is compared with the BM3D denoising algorithm, non-local means algorithm and bilateral filtering. The experimental results show that the proposed method not only improves the visual effect but also the value of structural similarity and feature similarity.
