Imaging"],"abstract":"<jats:p>Nighttime image dehazing presents unique challenges due to the unevenly distributed haze caused by the color change of artificial light sources. This results in multiple interferences, including atmospheric light, glow, and direct light, which make the complex scattering haze interference difficult to accurately distinguish and remove. Additionally, obtaining pairs of high-definition data for fog removal at night is a difficult task. These challenges make nighttime image dehazing a particularly challenging problem to solve. To address these challenges, we introduced the haze scattering formula to more accurately express the haze in three-dimensional space. We also proposed a novel data synthesis method using the latest CG textures and lumen lighting technology to build scenes where various hazes can be seen clearly through ray tracing. We converted the complex 3D scattering relationship transformation into a 2D image dataset to better learn the mapping from 3D haze to 2D haze. Additionally, we improved the existing neural network and established a night haze intensity evaluation label based on the idea of optical PSF. This allowed us to adjust the haze intensity of the rendered dataset according to the intensity of the real haze image and improve the accuracy of dehazing. Our experiments showed that our data construction and network improvement achieved better visual effects, objective indicators, and calculation speed.<\/jats:p>","DOI":"10.3390\/jimaging9080153","type":"journal-article","created":{"date-parts":[[2023,7,28]],"date-time":"2023-07-28T07:35:24Z","timestamp":1690529724000},"page":"153","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Nighttime Image Dehazing by Render"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8466-7520","authenticated-orcid":false,"given":"Zheyan","family":"Jin","sequence":"first","affiliation":[{"name":"State Key Laboratory of Extreme Photonics and Instrumentation, Zhejiang University, Hangzhou 310027, China"}]},{"given":"Huajun","family":"Feng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Extreme Photonics and Instrumentation, Zhejiang University, Hangzhou 310027, China"}]},{"given":"Zhihai","family":"Xu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Extreme Photonics and Instrumentation, Zhejiang University, Hangzhou 310027, China"}]},{"given":"Yueting","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Extreme Photonics and Instrumentation, Zhejiang University, Hangzhou 310027, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,28]]},"reference":[{"key":"ref_1","unstructured":"Jing, Z., Yang, C., and Wang, Z.
