Abstract (not part of the original publication): We construct a wavelet image coder based on the filter pair [1 2 1] and [-1 2 -1], and their (approximate) inverses. The use of these simple filters makes the transform (or inverse transform) extremely efficient, and thus useful for applications that involve asymmetric computational resources. A standard example is a centralized image database, in which the encoder need not be particularly efficient, but the decoder must be implemented on millions of platforms of low computational power. The opposite is true on a remote space exploration probe, in which limited computational resources require a very simple encoding algorithm, but the ground station can use a more computationally expensive decoding scheme.
