基于多流去噪网络的高光谱图像去噪

Hyperspectral Image Denoising Based On Multi-Stream Denoising Network

Yan Gao, Feng Gao, Junyu Dong

摘要:

高光谱图像在军事、农业、环境监测等领域有着广泛的应用。尽管如此,HSI在采集过程中通常会遭受各种类型的噪音。因此,去噪对于HSI分析和应用至关重要。本文提出了一种基于多流去噪网络(MSDNet)的HSI盲去噪方法。我们的网络由噪声估计子网络和去噪子网络组成。在噪声估计子网络中,设计了多尺度融合模块,从不同尺度捕获噪声。然后,利用去噪子网络得到最终的去噪图像。提出的MSDNet可以获得鲁棒的噪声水平估计,这是能够提高HSI去噪的性能。在HSI数据集上的大量实验表明,该方法优于四种密切相关的方法。

英文摘要:

Hyperspectral images (HSIs) have been widely applied in many fields, such as military, agriculture, and environment monitoring. Nevertheless, HSIs commonly suffer from various types of noise during acquisition. Therefore, denoising is critical for HSI analysis and applications. In this paper, we propose a novel blind denoising method for HSIs based on Multi-Stream Denoising Network (MSDNet). Our network consists of the noise estimation subnetwork and denoising subnetwork. In the noise estimation subnetwork, a multiscale fusion module is designed to capture the noise from different scales. Then, the denoising subnetwork is utilized to obtain the final denoising image. The proposed MSDNet can obtain robust noise level estimation, which is capable of improving the performance of HSI denoising. Extensive experiments on HSI dataset demonstrate that the proposed method outperforms four closely related methods.
