A Simplified Scalable Wavelet Video Codec with MCTF Structure

In recent years, wavelet-based image and video coding systems that utilize a wide range of spatial-temporal-SNR scalability with state-of-the-art coding performance has been proposed in the literature. The strong market acceptance of the new scalable technology stems from advances in network technology as well as various requirements from terminal users since computer network is becoming the main media transmission. This paper presents a simplified scalable wavelet video coding structure using MCTF with 5/3 filter. This structure does not include motion estimation, hence entropy coding for motion vectors is omitted. The proposed codec generates four temporal resolution layers, with up to four spatial resolution levels and six variable quantization levels for certain sequence. Simulation results show the codec has great flexibility feature and the reconstructed video quality is thought to be of acceptable quality
