Abstract
This article presents a single-loop approach to a 2-D discrete wavelet transform that allows processing infinitely high-image strip-maps. The paper gradually compares several computational strategies to finally show how to deal with a multi-scale wavelet transform of infinite image streams. Besides, the transform is followed by a bit-plane encoder which also processes data in a single loop. The whole machinery is part of a CCSDS 122.0 image codec which manages to process a single pixel in about 33 ns on a contemporary desktop computer, without the contribution of any parallel computing or SIMD vectorization.
