Based on the compact support property of popular DWT filters

a low-memory implementation of DWT called the Stripe-Based DWT(SBWT)is proposed

which produces the same subband coefficients as the global implementation of DWT.Additionally

the production of subband coefficients lends itself to PCT-based image coders in that no intermediate buffering is needed between the SBWT and the coders.When coupled with PCT-based image codec’s and 5-level decomposition with the CDF 9/7 filter bank

the overall memory reductions are 18.4% and 17.9% compared with the line-based DWT (LBWT) and the memory-constrained WT

respectively.
