Abstract This paper presents a new algorithm that utilizes wavelet for color image coding.After wavelet decomposing and scalar quantization,Y,Cr,Cb components are coded separately using duplicate tree coding algorithm whicn can compress the high frequency subbands effectively.Experimental results show that the new algorithm is very practical and with good performance for color image coding.
