Data Compression Conference (DCC)
作者: D.E. Ba V.K. Goyal Massachusetts Institute of Technology USA
Summary form only given. We designed a family of integer-to-integer (i2i) approximations to the Cartesian-to-polar transformation and analyzed its behavior for high-rate transform coding. Denoting (ordinary, continuou... 详细信息

Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC)
作者: Jeffrey Tsao Michael S. Hansen Sebastian Kozerke Central Technologies Novartis Institutes of BioMedical Research Inc. Cambridge MA USA Cardiothoracic Unit UCL Institute of Child Health Great Ormond Street Hospital London UK Institute for Biomedical Engineering University and Swiss Federal Institute of Technology Zurich Switzerland
The theory and implementation of the k-t approach (k-t BLAST and k-t SENSE) are reviewed in the context of transform coding. The k-t approach exploits the information redundancy in typical time series of magnetic reso... 详细信息
