ABSTRACT
The past decade has seen increased sophistication and maturity of wavelet-based image compression technologies. Within the family of mathematical transforms for image coding, discrete wavelet transform has unseated discrete cosine transform (DCT) [127-129] as the transform of choice. The wavelet-based JPEG 2000 international standard for still image compression [130] not only obtains superior compression performance over the DCT-based old JPEG standard [129], but also offers scalability advantages in reconstruction quality and spatial resolution that are desirable features for many consumer and network applications.
