On a bound on signal-to-noise ratio in subband coding of Gaussian image process
The purpose of this paper is to analyze a bound on signal-to-noise ratio SNR in subband coding of Gaussian image process. For the proposed method optimization distortion-rate function as a fidelity measure is applied. The theoretical 1imit of a bound on SNR is obtained to be about 52 dB for a given Gaussian image power spectral density. The proposed method requires low computer cost because of its complexity compared to some other subband coding schemes.
