In order to improve this kind of images, in this paper, a low-light sensor image enhancement algorithm based on HSI color model is proposed. At first, we propose a dataset generation method based on the Retinex model to overcome the shortage of sample data. Then, the original low-light image is transformed from RGB to HSI color space. The segmentation exponential method is used to process the saturation (S) and the specially designed Deep Convolutional Neural Network is applied to enhance the intensity component (I). At the end, we back into the original RGB space to get the final improved image. Experimental results show that the proposed algorithm not only enhances the image brightness and contrast significantly, but also avoids color distortion and over-enhancement in comparison with some other state-of-the-art research papers. So, it effectively improves the quality of sensor images.<\/jats:p>","DOI":"10.3390\/s18103583","type":"journal-article","created":{"date-parts":[[2018,10,23]],"date-time":"2018-10-23T12:43:36Z","timestamp":1540298616000},"page":"3583","source":"Crossref","is-referenced-by-count":26,"title":["A Low-Light Sensor Image Enhancement Algorithm Based on HSI Color Model"],"prefix":"10.3390","volume":"18","author":[{"given":"Shiping","family":"Ma","sequence":"first","affiliation":[{"name":"Aeronautics Engineering College, Air Force Engineering University, Xi\u2019an 710038, China"}]},{"given":"Hongqiang","family":"Ma","sequence":"additional","affiliation":[{"name":"Aeronautics Engineering College, Air Force Engineering University, Xi\u2019an 710038, China"}]},{"given":"Yuelei","family":"Xu","sequence":"additional","affiliation":[{"name":"Aeronautics Engineering College, Air Force Engineering University, Xi\u2019an 710038, China"},{"name":"Unmanned System Research Institute, Northwestern Polytechnical University, Xi\u2019an 710072, China"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-7562-9220","authenticated-orcid":false,"given":"Shuai","family":"Li","sequence":"additional","affiliation":[{"name":"Aeronautics Engineering College, Air Force Engineering University, Xi\u2019an 710038, China"}]},{"given":"Chao","family":"Lv","sequence":"additional","affiliation":[{"name":"Aeronautics Engineering College, Air Force Engineering University, Xi\u2019an 710038, China"}]},{"given":"Mingming","family":"Zhu","sequence":"additional","affiliation":[{"name":"Aeronautics Engineering College, Air Force Engineering University, Xi\u2019an 710038, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"587","DOI":"10.1016\/S0030-3992(03)00078-1","article-title":"CMOS vs. CCD sensors in speckle interferometry","volume":"35","author":"Helmers","year":"2003","journal-title":"Opt.
