Abstract :
This work presents a new image coding scheme based on multiwavelet filter banks. First, 2D multiwavelet decomposition is performed on original image. Then, several hierarchical trees are constructed in transform domain, and an extension of set partitioning in hierarchical trees algorithm is proposed to quantize multiwavelet coefficients. Our simulation shows that this scheme is effective and promising
