Abstract

fetched live from OpenAlex

Video super-resolution(VSR) upscales a low-resolution video to the higher one. Most applications require compression of the super-resolved video due to limited internet bandwidth and storage capacity. However, most studies on VSR techniques have focused only on improving image quality, ignoring the impact of the compression process on visual quality. Consequently, even a VSR with good visual quality has a risk of significant loss of quality when serviced online or stored as a file. To address this problem, we propose an encoding-aware VSR framework. In the framework, we created a differentiable virtual codec to estimate the bit rate and used it for the loss function, which optimizes the super-resolved videos by considering the rate-distortion trade-off relationship and eventually leads to the prevention of visual quality degradation. According to the results, our real-time VSR model for x4 upscaling, trained with 1,191K parameters, yields a maximum gain of 13.2% over state-of-the-art VSR models based on the Bjøntegaard delta rate.

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.
