The authors developed two computer models to judge video quality: one that compares a bad video to its original version (full-reference) and one that works without seeing the original (no-reference). The full-reference model uses a special technique called Swin-B to measure differences between videos. The no-reference model analyzes video frames individually using two methods, combines the results, and predicts quality without needing the original. Their full-reference model won first place in a competition, and their no-reference model ranked fourth, showing their methods work well.

Abstract
This report presents our solutions to the QoMEX 2026 Grand Challenge on Video Quality Assessment for Asymmetric Encoded Videos, comprising a full-reference (FR) model, CompressedVQA-AEV-FR, and a no-reference (NR) model, CompressedVQA-AEV-NR. The FR approach leverages a Swin-B backbone to extract multi-stage similarity statistics between reference and distorted videos for quality prediction. For the NR setting, our model employs complementary frame-level encoders based on SigLIP2 and Swin-B, followed by temporal mean pooling and cross-fold ensembling to estimate perceptual quality without reference data. Our CompressedVQA-AEV-FR achieves first place in the FR track of QoMEX 2026 Grand Challenge, while CompressedVQA-AEV-NR secures fourth place in the NR track, demonstrating the effectiveness of our proposed models.
