Abstract :
A new multirate image subband coding scheme for backward coding of wavelet trees (BCWT) is presented. Fully utilizing the multirate characteristic of wavelet subband decomposition, BCWT inherently provides resolution-scalability for resolution-progressive decoding. With the proposed coding scheme, BCWT can also be adjusted to provide rate-scalability for quality-progressive decoding. More importantly, resolution-scalability is retained. Compared with current state-of-the-art JPEG2000 image coding, BCWT has much lower complexity and performs more than 6 times faster
