Abstract
A predictive vector quantization (PVQ) structure is proposed,
where the encoder uses a predictor based on an intrablock support
region, followed by a modified vector quantizer stage. Simulation results
show that a modification on a previously published PVQ system led to an
improvement of 1 dB in PSNR for Lenna.
