A R-D optimization based MPEG -2 quantization algorithm
. In this paper, a R-D optimization based decision region adaptive algorilhm f i r MPEG-2 quantizer is pre.wn/ed The decision level of quantizer is adaptively selected hy searching the minimrrii R-D Lagrangian cost, taking into consideration of' the dis/rihir/ion of inpnt soiirce. This approach makes the R-D characteristic of' yirantizer has an estirnahle improvement. The PSNR for htminance and chrominance components can he increased by 0.5 dB and 0. I dB respectively in comparision wit/i the TM.5 qirantization method'. Index Ternis -MPEG-2 quantizer, TM5, Source distribution, Region adaptive quantization
