In order to remove integration drift, this research presents DeRO, a unique dead reckoning architecture that replaces the conventional function of accelerometers as the principal sensor for position determination with the Doppler velocity of a 4D FMCW radar. It incorporates this with gyroscope data and updates a Kalman filter using accelerometer tilt and radar range measurements. By lowering position error by 47%, this system performs noticeably better than the most advanced radar-inertial techniques.

This paper establishes a benchmark for 3D content-based image retrieval (CBIR) in medical imaging using the TotalSegmentator dataset. It evaluates supervised embeddings trained on medical images against self-supervised embeddings from non-medical datasets, testing retrieval at both organ and region levels. By introducing a late interaction re-ranking method inspired by text retrieval, the study achieves near-perfect recall across diverse anatomical structures. The results provide a much-needed benchmark and roadmap for future development of AI-powered medical image retrieval systems, enabling more reliable, precise, and efficient radiology workflows.

The conference’s Singapore debut is expected to be its largest and the first major in-person crypto conference in the region.
