Transforms for Wyner-Ziv Coding of Video
msra
摘要
Orthonormal transforms for the Distributed Source Coding of video are discussed. A theoretical framework is provided, and experiments are performed to investi- gate the benefits of such transforms. These results are compared to previous systems without transforms for distributed sources. The authors define the EigenVec- tor Transform (EVT) and compare it's performance to the more traditional Discrete Cosine Transform. Re- sults indicate that transforms can improve compres- sion by exploiting the spatial correlation at the en- coder, but complexity issues must still be resolved.
