In this paper, a novel image enhancement method based on HE and adaptive gamma correction with weight distribution (AGCWD) is proposed for natural and effective image enhancement. In this method, histogram stretching is performed on Red\u2013Green\u2013Blue (RGB) color components of image, and then the color space of RGB image is converted to Hue\u2013Saturation\u2013Intensity (HSI) color space. The histograms of S and I components are divided into sub-histograms according to the exposure threshold. The underexposure regions are enhanced with a new AGCWD. Then, the color space of HSI image is converted to RGB color space. Finally, the HE is applied to the input image with the obtained image histogram map. Thus, the method has not only effectively prevented the over-enhancement of the contrast but also obtained the quality and natural enhanced image. The proposed method is compared with the most known contrast enhancement methods and low-light enhancement methods. Experimental results have supported that the proposed method outperforms other methods in terms of both visual perception and objective evaluation. <\/jats:p>","DOI":"10.1142\/s0218001423540125","type":"journal-article","created":{"date-parts":[[2023,5,25]],"date-time":"2023-05-25T08:47:28Z","timestamp":1685004448000},"source":"Crossref","is-referenced-by-count":9,"title":["A Hybrid Method for Enhancement of Both Contrast Distorted and Low-Light Images"],"prefix":"10.1142","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7766-6757","authenticated-orcid":false,"given":"Nurullah","family":"Ozturk","sequence":"first","affiliation":[{"name":"Department of Computer Technologies, Vocational College, Kayseri University, Kayseri 38280, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Serkan","family":"Ozturk","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Erciyes University, Kayseri 38039, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2023,7,6]]},"reference":[{"key":"S0218001423540125BIB001","first-page":"607","volume-title":"Proc.
