In Magnetic Resonance Imaging (MRI) studies, for clinical applications and for research as well, reduction of scanning time is an essential issue. This time reduction could be obtained by using fast acquisition sequences, such as EPI and spiral k-space trajectories, and by acquiring less data, this being possible based on the new sampling theories that gave rise to the so called Compressed Sampling...
Synthetic aperture radar (SAR) data collections can cover large areas at high resolution, generating massive amounts of data. Many existed transform-based compression techniques can effectively reduce the costs of storage and transmission with slight loss of information. As a new developed multi-resolution geometry analysis tool, Bandelet can make full use of intrinsic geometry regularity of images...
