Probabilistic Semantic Mapping for Autonomous Driving in Urban Environments

Sensors, 2023
Statistical learning techniques and increased computational power have facilitated the development of self-driving car technology. However, a limiting factor has been the high expense of scaling and maintaining high-definition (HD) maps. These maps are a

On Capturing Semantics in Ontology Mapping [PDF]

World Wide Web, 2008
Semantic interoperability between disparate systems in open, distributed environments has become the quest of many practitioners in a variety of fields. One way to achieve such a goal is through ontology mapping. The perspective users of such technology, however, are faced with a number of challenges including ambiguity of the meaning of mappings ...

Multiscale and multidirection depth map super resolution with semantic inference

IET Image Processing, 2023
Depth map super resolution has been paid much attention in 3D applications due to the limitation of depth sensors. Few textures in objects with clear contours along them is the most important characteristic of depth map. An efficient image representation
