In many real-world scenarios, video data acquired by image sensors are often compressed for efficient transmission and storage, which introduces compression artifacts and degrades both visual quality and downstream task performance. This issue is especially significant in sensor-based systems such as surveillance cameras and mobile imaging devices. To address these challenges, we propose a novel joint human\u2013machine video enhancement framework for compressed video enhancement that jointly targets human perceptual quality and machine vision performance. The framework integrates four complementary components: a Spatio-Temporal Fusion Module that leverages inter-frame correlations, a High-Frequency Semantic Fusion module for recovering structurally important details relevant to machine tasks, a Texture-Guided Model that enhances low-level visual features, and a Refined Attention Residual Quality Enhancement Module that adaptively emphasizes salient regions. By progressively combining these modules, the framework effectively restores compressed content while preserving task-relevant semantics. The experimental results demonstrate that our method consistently outperforms existing approaches, achieving higher PSNR and SSIM as well as improved object detection and video object segmentation performance. These results highlight the framework\u2019s practical applicability for compressed video enhancement in sensor-based systems, including intelligent surveillance and autonomous imaging platforms.<\/jats:p>","DOI":"10.3390\/s26113494","type":"journal-article","created":{"date-parts":[[2026,6,1]],"date-time":"2026-06-01T17:11:01Z","timestamp":1780333861000},"page":"3494","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Multi-Module Fusion Framework for Restoring Human and Machine Vision Quality in Compressed Video"],"prefix":"10.3390","volume":"26","author":[{"given":"Keren","family":"He","sequence":"first","affiliation":[{"name":"Graduate School of Science and Engineering, Hosei University, Tokyo 184-8584, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Xiang","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Engineering, Hosei University, Tokyo 184-8584, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yufei","family":"Gao","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Engineering, Hosei University, Tokyo 184-8584, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Yu","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Engineering, Hosei University, Tokyo 184-8584, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5078-0522","authenticated-orcid":false,"given":"Jinjia","family":"Zhou","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Engineering, Hosei University, Tokyo 184-8584, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,1]]},"reference":[{"key":"ref_1","first-page":"3523","article-title":"Image segmentation using deep learning: A survey","volume":"44","author":"Minaee","year":"2021","journal-title":"IEEE Trans.
