Abstract

The Chandrayaan 3 (Ch-3) mission, as of the day (23rd of August 2023), is all set to explore the moon’s surface in great detail. Scientists have carefully chosen the landing site based on data gathered from previous missions, namely Chandrayaan 2’s (Ch-2) Imaging Infrared Spectrometer (IIRS) and Chandrayaan 1’s (Ch-1) Moon Mineralogy Mapper (M3). Our research analyzes the data from the selected Ch-3 landing site by using sophisticated techniques to remove unwanted noise from the hyperspectral images provided by IIRS and M3. The IIRS on Ch-2 and M3 on Ch-1 captured valuable information differently, giving us a better understanding of the moon’s composition and features. We aim to improve the quality of the Ch-3 landing site data by eliminating any interference caused by noise, making the images clearer and more useful. To achieve this, we’re employing two denoising methods- HyRes (Automatic Hyperspectral Image Restoration Using Sparse and Low-Rank Modeling) and HyMiNoR (Hyperspectral Mixed Gaussian and Sparse Noise Reduction). These smart algorithms will help us reveal the true nature of the lunar landscape hidden beneath the noise, giving us better insights into the landing site’s characteristics.

Abstract Image

根据 Ch-1 M3 和 Ch-2 IIRS 数据对 Manzius U 和 Boguslawsky M 月面环形山之间的高光谱斑块进行去噪处理
截至目前(2023 年 8 月 23 日),"月壤 3 号"(Chandrayaan 3,Ch-3)任务已准备就绪,将对月球表面进行深入细致的探索。科学家们根据以往任务收集的数据,即 "月壤 2 号"(Ch-2)的成像红外分光仪(IIRS)和 "月壤 1 号"(Ch-1)的月球矿物学绘图仪(M3),精心选择了着陆点。我们的研究通过使用复杂的技术,从 IIRS 和 M3 提供的高光谱图像中去除不必要的噪音,从而对选定的 Ch-3 着陆点的数据进行分析。Ch-2上的IIRS和Ch-1上的M3捕捉到了不同的有价值信息,让我们更好地了解了月球的组成和特征。我们的目标是提高 Ch-3 着陆点数据的质量,消除噪音干扰,使图像更清晰、更有用。为此,我们采用了两种去噪方法--HyRes(使用稀疏和低等级建模的自动高光谱图像复原)和 HyMiNoR(高光谱混合高斯和稀疏降噪)。这些智能算法将帮助我们揭示隐藏在噪声之下的月球景观的真实面貌,让我们更好地了解着陆点的特征。
