Applications of fractals to image data compression
… and DPCM. Fractal techniques based on the use of space-filling curves are developed as a mechanism for hierarchical application of conventional techniques. Two particular applications are highlighted: the re-ordering of data during image scanning and the mapping of multi-dimensional data to one …

On the construction of some capacity-approaching coding schemes
… channel bandwidth, joint coding schemes based on space-filling curves and other families of curves are proposed. For uniform sources and modulo channels, our coding scheme based on space-filling curves operates within 1.1 dB of Shannon's rate-distortion bound. For Gaussian sources and additive …

A distributed multi-threaded data partitioner with space-filling curve orders
… on each process in the communication group. Space-filling curves are used to permute data - Morton order is the default curve. For dimensions <=3, we have options to generate Hilbert-like curves. Two metrics used to determine partitioning overheads are memory consumption and execution time, …

Dynamic Load Balancing for a hp-adaptive Discontinuous Galerkin Wave Equation Solver via Spacing-Filling Curve and Advanced Data Structure
… the performance of the supercomputers. A space-filling curve (SFC) based repartitioning algorithm is implemented in this work. The algorithm is designed to execute quickly in parallel. Its low memory overhead is beneficial to distributed memory systems. Additionally, the high-quality …
