摘要 为了研究不可分小波在图像压缩中的应用,利用陪集构造方法构造了一种特殊的二元不可分双正交小波:梅花小波,并将其和 SPIHT 编码相结合研究了其在图像压缩中的性能。该算法可以实现无浮点的乘法运算,运算速度快,易于硬件设计。 Nonseparable wavelet is a new research field in image compression.Aspecial two dimensional nonseparable wavelet:quincunx wavelet is constructed,using algorithm coset by coset(CBC).It is used in image compression together with SPIHT algorithm and the performance of its compression is discussed.This algorithm can be completed by no float multiplication operation.It has fast operation rate and is easy to be implemented in hardware.
