Predictive vector quantization with intrablock prediction support region
Aldebaro Barreto da Rocha Klautau Junior · IEEE Transactions on Image Processing · 1999
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.
