Abstract
A fast method with logarithmic complexity for image compression and expansion is provided, implementable on the Geometric Arithmetic Parallel Processor (GAPP) or any similar fine-grained, mesh-connected Single Instruction-Multiple Datastream (SIMD) array processor. Efficient decomposition of the original image into multiple subimages enables the method to exploit the parallelism of the SIMD computer for implementing powerful multiresolution pyramid and hierarchical image processing techniques on a massively parallel processor.
