Abstract

fetched live from OpenAlex

A new prediction structure for coding multi-view video streams is presented. In general, for free viewpoint TV (FTV) applications, it is necessary that multi-view videos are efficiently compressed before transmission. Our algorithm synthesizes extra video streams and uses them as extra references when coding the original views. These streams are synthesized based on the already encoded frames from neighboring views, without requiring the scene's depth information. The proposed scheme utilizes both motion and disparity compensation methods to exploit temporal and inter-view correlation within each view sequence and among views, respectively. To guarantee the best bitrate performance, our algorithm adaptively re-sorts the reference frame list, such that minimum number of bits is used for coding reference frame indices. Performance evaluations show that our proposed coding method outperforms the recent multiview coding standard by up to 1 dB PSNR and enhances the compression ratio by 22.97%.

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.
