Reducing the Wavelet Ringing Artifacts in a Low-Complexity Video Codec

A low-complexity wavelet-based video coding technique is proposed. The devised technique adopts JPEG-2000 image coding. The wavelet transformation and subband quantization are developed and optimized in order to reduce the ringing artifacts especially at very low bit rate. The proposed coding technique reduces the coding complexity and performs well at average PSNR. As compared to other rival coding methods the proposed coding policy has a good compression ratio and an improved visual quality
