dc.description.abstract | Semantic segmentation represents a promising means to unify different detection tasks, especially pixelwise traversability perception as the fundamental enabler in robotic vision systems aiding upper-level
navigational applications. However, major research efforts are being put into earning marginal accuracy increments on semantic segmentation benchmarks, without assuring the robustness of real-time
segmenters to be deployed in assistive cognition systems for the visually impaired. In this paper, we
explore in a comparative study across four perception systems, including a pair of commercial smart
glasses, a customized wearable prototype and two portable RGB-Depth (RGB-D) cameras that are being
integrated in the next generation of navigation assistance devices. More concretely, we analyze the gap
between the concepts of “accuracy” and “robustness” on the critical traversability-related semantic scene
understanding. A cluster of efficient deep architectures is proposed, which are built using spatial factorizations, hierarchical dilations and pyramidal representations. Based on these architectures, this research
demonstrates the augmented robustness of semantically traversable area parsing against the variations
of environmental conditions in diverse RGB-D observations, and sensorial factors such as illumination,
imaging quality, field of view and detectable depth range. | en |
