Abstract

fetched live from OpenAlex

With fast developments in video broadcasting and communication, high definition and high bit rate video applications with low latency are becoming more and more popular. This leads to the emergence of the intra-only encoding scheme as it can provide the required performance. Specific to these applications, a novel intra-only video coding algorithm is proposed in this paper. A node-cell macroblock pixel structure is defined and a 2-D interleaved DCT is proposed to encode the node pixels. The proposed algorithm introduces several new intra coding modes based on the proposed node-cell macroblock pixel structure. Combined with the existing MPEG-4 AVC intra coding modes, the proposed algorithm implements the mode decision through a rate distortion optimization process. To evaluate the performance, the proposed coding algorithm is integrated into the reference MPEG4-AVC codec. Experimental results confirm that the new coding algorithm can provide significant rate distortion performance gain over the reference MPEG-4 AVC codec.

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.
