Abstract

fetched live from OpenAlex

Augmented reality devices require multiple sensors to perform various tasks\nsuch as localization and tracking. Currently, popular cameras are mostly\nframe-based (e.g. RGB and Depth) which impose a high data bandwidth and power\nusage. With the necessity for low power and more responsive augmented reality\nsystems, using solely frame-based sensors imposes limits to the various\nalgorithms that needs high frequency data from the environement. As such,\nevent-based sensors have become increasingly popular due to their low power,\nbandwidth and latency, as well as their very high frequency data acquisition\ncapabilities. In this paper, we propose, for the first time, to use an\nevent-based camera to increase the speed of 3D object tracking in 6 degrees of\nfreedom. This application requires handling very high object speed to convey\ncompelling AR experiences. To this end, we propose a new system which combines\na recent RGB-D sensor (Kinect Azure) with an event camera (DAVIS346). We\ndevelop a deep learning approach, which combines an existing RGB-D network\nalong with a novel event-based network in a cascade fashion, and demonstrate\nthat our approach significantly improves the robustness of a state-of-the-art\nframe-based 6-DOF object tracker using our RGB-D-E pipeline.\n

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
