However, hyperspectral images are often affected by stripe noise, which affects image quality and accuracy. Therefore, this paper aims to study the method of stripe noise removal in hyperspectral images and apply it to actual data.This paper first introduces hyperspectral imaging and its application scenarios, and then analyzes the characteristics and causes of stripe noise in hyperspectral images in detail. Then, the current methods for stripe noise removal are reviewed and evaluated. Based on this, this paper proposes a stripe noise removal method based on wavelet transform and mean filtering, and conducts experimental verification.The experimental results show that the method proposed in this paper has a good effect in removing stripe noise in hyperspectral images. At the same time, this paper discusses the applicability and shortcomings of the method and proposes improvement directions.Keywords: hyperspectral imaging, stripe noise, wavelet transform, mean filtering
