Target-Guided Query Allocation and Boundary-Aware Multi-Scale Feature Fusion for Object Detection in UAV Imagery

Object detection in unmanned aerial vehicle (UAV)-based visual sensing is important for aerial monitoring and intelligent perception. However, UAV imagery often contains small and densely distributed objects, complex backgrounds, and substantial scale variations. Repeated downsampling weakens the boundary and localizat...

Compact Robot Policies Need Fine-Grained Visual Representations

Multi-task manipulation policies differ in architecture, scale, and pretrained priors all at once, so published comparisons cannot attribute performance to any single component. We argue that most of it comes from the visual representation, and that parameter scale and generative priors are largely incidental. To test...
