RRCNN-EM: A Deep Learning Framework for Hyperspectral Road Surface Segmentation to Enhance Automotive Safety
Main Article Content
Abstract
Recent advances in hyperspectral imaging technology have created new opportunities for enhancing
roadway safety through automated surface-condition monitoring. Traditional road inspection techniques,
relying on RGB or infrared imagery, often fail to distinguish visually similar materials such as dry
pavement, oil spills, water films, or surface cracks – conditions that significantly affect vehicle traction
and traffic safety. To address these limitations, this research proposes a recurrent residual convolutional
neural network with ensemble modeling (RRCNN-EM) for hyperspectral road-surface segmentation and
hazard classification. The proposed framework integrates a Weiner filter for denoising hyperspectral data,
followed by RRCNN-based segmentation to preserve spatial dependencies and handle high-dimensional
spectral information.
