Quantifying Volumetric Risk: Class-Aware Asymmetric Weighted Conformal Prediction for 3D Medical Image Segmentation

Reliable volumetric segmentation is critical for clinical diagnostics, yet foundation models such as MedSAM remain deterministic and lack calibrated uncertainty under distribution shift. Existing conformal prediction methods offer statistical guarantees but are frequently applied in 2D and assume symmetric error distri...

Template-Search Domain Adaptation via Multi-Stage Feature Alignment for Cross-Modal Object Tracking

Visual object tracking typically assumes that the initial template and subsequent search frames share the same sensing modality. In practice, sensor availability or operation may change over time, creating a substantial representation gap between template and search frames. Unlike conventional multi-modal tracking wher...

Vision-Based Perception of UAV Targets Under Synthetic Fog: A Task-Oriented Evaluation

A task-driven evaluation framework that links depth-aware synthetic fog generation, image restoration, object detection, and tracking within a unified pipeline shows that restoration quality does not necessarily translate into proportional gains in downstream perception and therefore should be evaluated jointly with de...
