Accurate models like Faster R-CNN incur latencies exceeding 100 ms per frame and lack integrated routing for disabled users. To address these shortcomings, this study proposes a hybrid YOLOv10–Faster R-CNN framework that sequentially applies You Only Look Once (YOLOv10) (operating at 45 fps) for initial mobility-aid localization and Faster R-CNN for bounding-box refinement, with a confidence-weighted fusion module to suppress false positives without compromising recall. By augmenting this dual-stage detection pipeline with an ensemble voting classifier that predicts traffic severity from refined detections and live intelligent transportation systems (ITSs) density metrics, the proposed system delivers the first end-to-end solution for real-time, accessibility-aware route planning tailored to wheelchair and crutch users—a capability previously unaddressed by standalone object-detection or traffic-management methods. We validate our approach on three complementary datasets – real-time urban traffic feeds, a diverse mobility-aid image corpus (wheelchairs, crutches), and a wheelchair-specific subdataset – and evaluate performance through mean average precision (mAP), recall, inference latency, traffic-prediction accuracy, and disabled-user travel-time reduction. The hybrid model achieves 99.4% mAP for general mobility aids and 98.9% mAP for wheelchairs, attains 100% recall (a 23.46% increase in true-positive detections over standalone baselines), and maintains an end-to-end latency of 22 ms per frame (<span><math><mrow><mo>≈</mo><mn>45</mn><mi>f</mi><mi>p</mi><mi>s</mi></mrow></math></span>).

However, current state-of-the-art models—primarily based on convolutional neural networks and transformers—depend on rigid feature hierarchies and large-scale annotated datasets. These architectures struggle to generalize across diverse lesion morphologies, rare dermatological presentations, and variations in skin tone or imaging modality. In this work, we introduce SKIN-ORBIT (Spectral-Kinetic Inference Network with Oscillatory Resonance-Based Inference Topology), a biologically inspired, signal-centric segmentation framework that redefines how spatial patterns are modeled. Rather than relying on fixed receptive fields or attention over patches, SKIN-ORBIT treats each pixel as a localized oscillatory emitter, producing dynamic waveform signals over time. These signals propagate through a deformable resonance field, where zones of persistent phase coherence emerge as lesion regions—identified via stable, constructive interference patterns. The framework is anchored by two core components: the Kinetic Deformation Unit (KDU), which modulates spatial topology through dynamic elastic distortions driven by pixel-wise kinetic energy profiles, enabling continuous and topology-aware field reshaping; and the Oscillatory Field Propagation (OFP) module, which replaces convolution and attention with harmonic signal propagation, simulating wavefront interactions across the spatial domain without predefined kernels. To facilitate unsupervised learning, we propose a novel Cross-Modal Resonance Coherence Loss (CMRCL), which enforces phase alignment across visible, ultraviolet (UV), and infrared (IR) imaging modalities. CMRCL computes spectral-phase divergence in the latent oscillatory domain and minimizes incoherence between modality-specific representations, encouraging shared structural resonance. SKIN-ORBIT was trained and validated on a dataset of 15,318 cross-spectrum dermatological images. It achieved 98.7% segmentation accuracy, a Dice coefficient of 0.92, Jaccard index of 0.86, sensitivity of 0.91, specificity of 0.97, and a Hausdorff Distance of 5.6 pixels—substantially outperforming traditional CNN and transformer-based models.
