Abstract: This paper proposes Intra frame coding for Advanced Video Coding Standard to control PSNR, bit rate and achieve high compression ratio using Gaussian pulse. Gaussian pulse, which improves the reconstructed image ie removes ringing, blocking artifacts and improves functionality of quantization. The Gaussian pulse operation smoothens the signal. Each Gaussian pulse multiplication scales the information content of the signal in a reversible way. The resulting signal would turn abstract. The proposed algorithm intra frame coding implemented using matlab. In the proposed algorithm Gaussian pulse applied before quantization block. The simulation results are presented using Matlab. The PSNR , compressed ratio and bit rate achived for Intra frames ie mother daughter frames, was presented for different quantization parameters with Gaussian scaling factor. The proposed algorithm gives better PSNR, compression ratio and low bit rate. The simulation results are obtained for yuv video sequences in CIF and QCIF format for different quantization parameters with Gaussian scaling factor. The simulation results are listed in table and represented rate distortion curve, compression ratio vs quantization parameter, and bit rate vs quantization parameter. The simulation results shows that the proposed algorithm achieve controlled reconstructed picture quality (PSNR), higher compression ratio and reduced bit rate.
