CGSA: Class-Guided Slot-Aware Adaptation for Source-Free Object Detection

Researchers introduce CGSA, a new framework for source-free domain adaptive object detection that integrates Object-Centric Learning into DETR-based detectors. The approach uses Hierarchical Slot Awareness and Class-Guided Slot Contrast modules to improve cross-domain object detection without retaining source data, demonstrating superior performance on multiple datasets.
