These low-light images will not only affect our observation but will also greatly affect the performance of computer vision processing algorithms. Low-light image enhancement technology can help to improve the quality of images and make them more applicable to fields such as computer vision, machine learning, and artificial intelligence. In this paper, we propose a novel method to enhance images through B\u00e9zier curve estimation. We estimate the pixel-level B\u00e9zier curve by training a deep neural network (BCE-Net) to adjust the dynamic range of a given image. Based on the good properties of the B\u00e9zier curve, in that it is smooth, continuous, and differentiable everywhere, low-light image enhancement through B\u00e9zier curve mapping is effective. The advantages of BCE-Net\u2019s brevity and zero-reference make it generalizable to other low-light conditions. Extensive experiments show that our method outperforms existing methods both qualitatively and quantitatively.<\/jats:p>","DOI":"10.3390\/s23239593","type":"journal-article","created":{"date-parts":[[2023,12,3]],"date-time":"2023-12-03T04:59:16Z","timestamp":1701579556000},"page":"9593","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["B\u00e9zierCE: Low-Light Image Enhancement via Zero-Reference B\u00e9zier Curve Estimation"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7527-0003","authenticated-orcid":false,"given":"Xianjie","family":"Gao","sequence":"first","affiliation":[{"name":"Department of Basic Sciences, Shanxi Agricultural University, Taigu 030801, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Zhao","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of New South Wales, Sydney, NSW 2052, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Han","sequence":"additional","affiliation":[{"name":"School of Sciences, Harbin University of Science and Technology, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinming","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Mathematical Sciences, Dalian University of Technology, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Shyni, H.M., and Chitra, E.
