GraphMapper: Efficient Visual Navigation by Scene Graph Generation
Zachary Seymour, Niluthpol Chowdhury Mithun, Han-Pang Chiu +2
Understanding the geometric relationships between objects in a scene is a core capability in enabling both humans and autonomous agents to navigate in new environments. A sparse, u…
MaAST: Map Attention with Semantic Transformersfor Efficient Visual Navigation
Zachary Seymour, Kowshik Thopalli, Niluthpol Mithun +3
Visual navigation for autonomous agents is a core task in the fields of computer vision and robotics. Learning-based methods, such as deep reinforcement learning, have the potentia…
RGB2LIDAR: Towards Solving Large-Scale Cross-Modal Visual Localization
Niluthpol Chowdhury Mithun, Karan Sikka, Han-Pang Chiu +2
We study an important, yet largely unexplored problem of large-scale cross-modal visual localization by matching ground RGB images to a geo-referenced aerial LIDAR 3D point cloud (…
Semantically-Aware Attentive Neural Embeddings for Image-based Visual Localization
Zachary Seymour, Karan Sikka, Han-Pang Chiu +2
We present an approach that combines appearance and semantic information for 2D image-based localization (2D-VL) across large perceptual changes and time lags. Compared to appearan…
Utilizing Semantic Visual Landmarks for Precise Vehicle Navigation
Varun Murali, Han-Pang Chiu, Supun Samarasekera +2
This paper presents a new approach for integrating semantic information for vision-based vehicle navigation. Although vision-based vehicle navigation systems using pre-mapped visua…
