Perceptually-Weighted Video Quality Metric for Asymmetric Encoded Sports Videos
Anna Meyer, Jonas Janzen, Diwakara Reddy +5
Objective video quality metrics commonly assume uniform spatial attention, an assumption that conflicts with the selective nature of human visual perception, particularly in sports…
Parallel Context Modeling for Sliding Window Attention in Neural Video Coding
Alexander Kopte, André Kaup
Most neural video codecs rely on temporal conditioning, which makes them susceptible to error propagation over long sequences. While Transformer-based architectures like the VCT of…
TAFA-GSGC: Group-wise Scalable Point Cloud Geometry Compression with Progressive Residual Refinement
Xiumei Li, Alexander Kopte, André Kaup
Scalable compression is essential for bandwidth-adaptive transmission, yet most learned codecs are optimized for a fixed rate-distortion point, making rate adaptation costly due to…
Sliding Window Attention for Learned Video Compression
Alexander Kopte, André Kaup
To manage the complexity of transformers in video compression, local attention mechanisms are a practical necessity. The common approach of partitioning frames into patches, howeve…
