Outdoor Pedestrian Navigation Using Boundary-Aligned Region and OpenStreetMap

IEEE Access
This paper addresses navigation for autonomous mobile robots operating in outdoor pedestrian environments and proposes a boundary-following navigation method that does not rely on semantic segmentation or prior exploration. The proposed method designates

A Semisupervised Approach Using the Adaptive Threshold Mechanism and Boundary-aware Learning for Radio-frequency Interference Segmentation

The Astrophysical Journal Supplement Series
In the task of radio-frequency interference (RFI) detection, the scarcity of high-quality labeled samples limits the performance of supervised models, while the severe class imbalance between background and RFI makes semisupervised methods prone to ...

Multi-level spatio-relational segformer (MLSRS-SegFormer): A novel vision transformer with adaptive spatial induction and dynamic positional encoding

MethodsX
Medical image segmentation is foundational to precision medicine. However, state-of-the-art Vision Transformers (ViTs) inherently suffer from a critical trade-off between comprehensive global contextualization and robust local boundary discrimination ...

Examination of the yaw-angle bias in three-dimensional boundary layers

, 2018
The investigation of three-dimensional boundary layers has recently been highly significant since this type of flows can occur, for instance, over highly swept wings of an aircraft. Therefore, researchers have been examining the aspects of these boundary layers by means of both theoretical and experimental studies.
