Bit Allocation Transfer for Perceptual Quality Enhancement of Traditional Video Codecs
Runyu Yang, Ivan V. Bajić
Traditional block-based video codecs, such as H.264/AVC, H.265/HEVC and H.266/VVC, rely on hand-crafted Rate-Distortion Optimization (RDO) processes that primarily minimize Mean Sq…
Context Adaptive Extended Chain Coding for Semantic Map Compression
Runyu Yang, Junqi Liao, Hyomin Choi +2
Semantic maps are increasingly utilized in areas such as robotics, autonomous systems, and extended reality, motivating the investigation of efficient compression methods that pres…
Understanding Rate-Distortion Performance in Distributed Transformer Inference
Anderson de Andrade, Alon Harell, Ivan V. Bajić
Transformers achieve superior performance on many tasks, but impose heavy compute and memory requirements during inference. This inference can be made more efficient by partitionin…
Lossy Common Information in a Learnable Gray-Wyner Network
Anderson de Andrade, Alon Harell, Ivan V. Bajić
Many computer vision tasks share substantial overlapping information, yet conventional codecs tend to ignore this, leading to redundant and inefficient representations. The Gray-Wy…
