# Wyner-Ziv theory for a general function of the correlated sources

@article{Yamamoto1982WynerZivTF, title={Wyner-Ziv theory for a general function of the correlated sources}, author={Hirosuke Yamamoto}, journal={IEEE Trans. Inf. Theory}, year={1982}, volume={28}, pages={803-807} }

A source coding problem is considered for the Wyner-Ziv type system where the decoder is required to estimate the value of some function of the encoder input and the side information. The rate-distortion function is established for this system, and for some binary cases parametric expressions are obtained to enable numerical calculations.
