Open AccessSubgraphs Matching-Based Side Information Generation for Distributed Multiview Video Coding
We adopt constrained relaxation for distributed multiview video coding (DMVC). The novel framework integrates the graph-based segmentation and matching to generate interview correlated side information without...

Lightweight Floating-Point Arithmetic: Case Study of Inverse Discrete Cosine Transform
To enable floating-point (FP) signal processing applications in low-power mobile devices, we propose lightweight floating-point arithmetic. It offers a wider range of precision/power/speed/area trade-offs, but...
