Abstract
A method of spatial domain image compression comprises splitting the image up into a plurality of 2*2 sub-blocks, and then compressing each sub-block where this can be done without unacceptable loss of detail by encoding it to either 1, 2, or 3 intensity values. On a second pass, the sub-blocks can themselves be concatenated into larger-sub-blocks, so achieving further compression, and those larger-sub-blocks can on a third pass be concatenated into still-larger-sub-blocks. The computational time required by the algorithm is low, both for compression and for decompression.
