The problem is heightened by the difficulty of detecting small and diverse litter objects across wide areas, prompting interest in Unmanned Aerial Vehicles (UAVs) and deep learning as viable solutions. We conducted a systematic literature review by initially using Google Scholar, and then iteratively expanding our search through bibliographic references to identify relevant studies and datasets. In this review, we: synthesize the applicability of nine publicly available litter datasets; compile and analyze computer vision integrations with Litter Management Systems, with a particular emphasis towards UAV-based solutions; and review relevant literature addressing this issue; among others. Our analysis includes four UAV-based datasets (BDW, UAVVaste, HAIDA, SODA) and five non-UAV datasets (TrashNet, TACO, MJU-Waste, PlastOPol, ZeroWaste), examining dataset characteristics, preprocessing techniques, model architectures, and evaluation metrics across studies. Our synthesis of the literature highlights the varied approaches different studies undertake, reflecting the complexity of the task and the absence of standardised protocols. We conclude by discussing priorities for future work, notably the need for more publicly available in-the-wild UAV-acquired datasets and the potential of newer model architectures to address current limitations in automated litter detection.<\/jats:p>","DOI":"10.1007\/s11042-026-21440-1","type":"journal-article","created":{"date-parts":[[2026,2,26]],"date-time":"2026-02-26T10:43:18Z","timestamp":1772102598000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Litter detection from aerial imagery: a review of UAV-based approaches and deep learning techniques"],"prefix":"10.1007","volume":"85","author":[{"given":"Matthias","family":"Bartolo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5996-4189","authenticated-orcid":false,"given":"Gabriel","family":"Hili","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dylan","family":"Seychell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Montebello","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carl J.","family":"Debono","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saviour","family":"Formosa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantinos","family":"Makantasis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,2,26]]},"reference":[{"key":"21440_CR1","unstructured":"United Nations DoE, Development SA-S (2015) Transforming our world: the 2030 agenda for sustainable development. https:\/\/sdgs.un.org\/2030agenda"},{"key":"21440_CR2","doi-asserted-by":"publisher","first-page":"498","DOI":"10.1016\/j.spc.2024.11.021","volume":"52","author":"PZ Oo","year":"2024","unstructured":"Oo PZ, Prapaspongsa T, Strezov V, Huda N, Oshita K, Takaoka M, Ren J, Halog A, Gheewala SH (2024) The role of global waste management and circular economy towards carbon neutrality.
