SHNet: A Lightweight Network Focusing on Shallow High-Resolution Features for PCB Defect Detection

Automatic defect detection for printed circuit boards (PCBs) is crucial for manufacturing quality and reliability, yet remains challenging due to tiny defect sizes, low visual contrast, and deployment constraints. We propose SHNet, a lightweight YOLOv8s-based detector that emphasizes shallow high-resolution representat...

ForesightNav: Adaptive Semantic-Geometric Planning for Universal Zero-Shot Goal-Oriented Navigation

ForesightNav is presented, a training-free universal zero-shot navigation framework that adaptively combines context-aware semantic value mapping, graph-based target verification, and TSP-based frontier ordering and results further support the effectiveness of adaptive switching, context-aware semantic mapping, and TSP...
