In this article, we propose a hybrid dual-branch model\u2014channel-spatial faster vision transformer (CSFVIT)\u2014that integrates local and global feature processing to enhance recognition performance under diverse occlusion scenarios. The local branch refines facial features using a parallel channel-spatial attention (PCSA) module based on ResNet-18, while the global branch leverages a faster vision Transformer (FasterViT) to capture long-range dependencies. A dynamic attention fusion (DAF) module adaptively balances these features based on occlusion severity. We validate our model on five benchmark datasets: CASIA-WebFace, LFW, Extended Yale B, ORL, and AR. The model achieves 97.46% accuracy on CASIA-WebFace, 97.62% on LFW, 99.39% on Extended Yale B, 98.78% on ORL, and 98.50% on AR (sunglasses)\/97.50% (scarf), consistently outperforming state-of-the-art baselines. CSFVIT achieves consistently high recognition accuracy under both synthetic and real-world occlusions, outperforming several attention- and transformer-based baselines. This practical and efficient architecture demonstrates strong potential for real-world face recognition applications in unconstrained environments.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hejazi, Elhamsadat, Majid Ahmadi, and Arash Ahmadi. &#8220;Robust Face Recognition and Classification Under Occlusion Using a Refined Transformer-Based Attention Mechanism.&#8221;\u00a0IEEE Canadian Journal of Electrical and Computer Engineering\u00a0(2026).
