Abstract

fetched live from OpenAlex

In this paper we present an approach for 6 DoF panoramic videos from omni-directional stereo (ODS) images using convolutional neural networks (CNNs). More specifically, we use CNNs to generate panoramic depth maps from ODS images in real-time. These depth maps would then allow for re-projection of panoramic images thus providing 6 DoF to a viewer in virtual reality (VR). As the boundaries of a panoramic image must touch in order to envelope a viewer, we introduce a border weighted loss function as well as new error metrics specifically tailored for panoramic images. We show experimentally that training with our border weighted loss function improves performance by benchmarking a baseline skip-connected encoder-decoder style network as well as other state-of-the-art methods in depth map estimation from mono and stereo images. Finally, a practical application for VR using real world data is also demonstrated.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
