Current detection technologies, such as human inspections and PCR\u2010based procedures, are time\u2010consuming and costly, limiting scalability. Convolutional neural networks (CNNs) like ResNet50 and VGG16 have shown promise for automating disease identification, but they struggle with generalization and collecting fine\u2010grained local and global information. In this study, we propose a deep learning solution based on a hierarchical vision transformer (HViT) model to detect poultry diseases from fecal images. We compare the performance of our HViT model with traditional CNNs (ResNet50, VGG16), lightweight architectures (MobileNetV3_Large_100, XceptionNet), and standard vision transformers (ViT) (ViT\u2010B\/16). The experimental results demonstrate that our HViT model outperforms other models, achieving an average validation accuracy of 90.90% with a validation loss of 0.2647. The HViT's ability to balance local and global feature recognition highlights its potential as a scalable solution for real\u2010time poultry disease detection. These findings underscore the significance of hierarchical attention in addressing complex image analysis tasks, with implications for broader applications in agriculture and medical imaging.<\/jats:p>","DOI":"10.1049\/ipr2.70115","type":"journal-article","created":{"date-parts":[[2025,5,25]],"date-time":"2025-05-25T23:54:58Z","timestamp":1748217298000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Modified Hierarchical Vision Transformer Model for Poultry Disease Detection"],"prefix":"10.1049","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9985-000X","authenticated-orcid":false,"given":"Michael Agbo Tettey","family":"Soli","sequence":"first","affiliation":[{"name":"Department of Computer Science University of Ghana  Accra Ghana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-1012-0710","authenticated-orcid":false,"given":"Dacosta","family":"Agyei","sequence":"additional","affiliation":[{"name":"Department of Computer Science University of Ghana  Accra Ghana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2954-1419","authenticated-orcid":false,"given":"Waliyyullah Umar","family":"Bandawu","sequence":"additional","affiliation":[{"name":"Department of Computer Science University of Ghana  Accra Ghana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8332-978X","authenticated-orcid":false,"given":"Leonard Mensah","family":"Boante","sequence":"additional","affiliation":[{"name":"Department of Computer Science University of Ghana  Accra Ghana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2798-4524","authenticated-orcid":false,"given":"Justice Kwame","family":"Appati","sequence":"additional","affiliation":[{"name":"Department of Computer Science University of Ghana  Accra Ghana"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"265","published-online":{"date-parts":[[2025,5,25]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.5875\/ausmt.v13i1.2439"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.3389\/fvets.2023.1174700"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.compag.2018.01.009"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.14569\/IJACSA.2021.0120295"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.51537\/chaos.1605529"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2025.3539122"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroscience.2025.01.020"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bspc.2025.107627"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rineng.2024.103692"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11633\u2010024\u20101393\u20108"},{"key":"e_1_2_10_12_1","first-page":"12","article-title":"Computer\u2010Aided Diagnostics of Heart Disease Risk PredictionUsing Boosting Support Vector Machine","author":"Owusu E.","year":"2021","journal-title":"Computational Intelligence and Neuroscience"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s42044-025-00231-1"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.48550\/arXiv.2012.12877"},{"key":"e_1_2_10_15_1","first-page":"11","article-title":"EfficientNetV2: Smaller Models and Faster Training","author":"Tan M.","year":"2021","journal-title":"Arxiv Preprint"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1109\/TPAMI.2022.3152247"},{"key":"e_1_2_10_17_1","unstructured":"A.Krizhevsky I.Sutskever andG.
