When experimentally tested with the JM 8.1a encoder on QCIF video sequences the algorithm provides 2.8% average bit rate saving with insignificant PSNR loss (around 0.13%) without computational complexity increase. Experiments indicate that the algorithm may also be adopted for higher bit rates.||Type of material:||Conference Publication||Keywords:||H.264; Lagrange multiplier; Low bit rate video coding||Language:||en||Status of Item:||Peer reviewed||Conference Details:||9th Irish Machine Vision and Image Processing Conference (IMVIP), Belfast, Northern Ireland, 30 - 31 August, 2005|
