However, small infrared targets are difficult to detect due to their weak brightness, small size and lack of shape, structure, texture, and other information elements. In this paper, we propose a target detection method. First, to address the problem that the proximity of targets to high\u2010brightness clutter leads to missed detection of candidate targets, a Gaussian differential filtering preprocessed image is used to suppress high\u2010brightness clutter. Second, a density\u2010peaked global search method is used to determine the location of candidate targets in the preprocessed image. We then use local contrast to the candidate target points to enhance the gradient features and suppress background clutter. The Facet model is used to compute multidirectional gradient features at each point. A new efficient surrounding symmetric region partitioning scheme is constructed to capture the gradient characteristics of targets of different sizes in eight directions, followed by weighting the candidate target gradient characteristics using the standard deviation of the symmetric region difference. Finally, an adaptive threshold segmentation method is used to extract small targets. Experimental results show that the method proposed in this paper has better detection accuracy and robustness compared with other detection methods.<\/jats:p>","DOI":"10.1049\/2024\/6814362","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T22:50:06Z","timestamp":1716850206000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Infrared Small Target Detection Based on Density Peak Search and Local Features"],"prefix":"10.1049","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1787-2978","authenticated-orcid":false,"given":"Leihong","family":"Zhang","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9857-1684","authenticated-orcid":false,"given":"Hui","family":"Yang","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1466-2542","authenticated-orcid":false,"given":"Qinghe","family":"Zheng","sequence":"additional","affiliation":[]},{"given":"Yiqiang","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Dawei","family":"Zhang","sequence":"additional","affiliation":[]}],"member":"265","published-online":{"date-parts":[[2024,5,27]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1049\/el:20092206"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1049\/el.2010.2066"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2013.2242477"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/LGRS.2018.2790909"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.patcog.2016.04.002"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1080\/14498596.2022.2140714"},{"key":"e_1_2_9_7_2","doi-asserted-by":"crossref","unstructured":"ZhouJ.
