Reliability-Gated Fusion of Consumer Head and Foot IMUs for Lower-Body 3D Pose

The channel-gated model is the most accurate of the authors' learned fusion arms on clean data and its gates suppress the natively biased foot-orientation channels on clean real data without test-time supervision and flag dropout bursts at 0.92-0.999 AUROC.

One Sensor, Whole Body - 3D Body Pose from a Single Consumer Earbud IMU

A multimodal capture pipeline is built that records four-view RGB-D video together with an AirPods head IMU and two Striv insole IMUs, synchronize the streams post-hoc, and generate pseudo-ground-truth with SAM 3D Body, yielding a 35-take single-subject benchmark spanning gait, turning, vertical, everyday, and clinical...

GeM-NR: Geometry-Aware Multi-View Editing for Nonrigid Scene Changes

GeM-NR is proposed, a fast and flexible training-free approach for general multi-view consistent image editing, including edits that drastically change the geometry and appearance of the scene, and is demonstrated to handle edits with significant changes in geometry and appearance.

3D-Consistent Multi-View Editing by Correspondence Guidance

Experimental results show that this approach significantly improves 3D consistency compared to existing multi-view editing methods, and enables high-quality Gaussian splat editing with sharp details and strong fidelity to user-specified text prompts.
