Joint Spatial-Angular Sparse Coding for dMRI with Separable Dictionaries
[article]
2017
arXiv
pre-print
Preserved Fulltext
Other Versions
Current reconstruction methods however, rely on an angular representation per voxel with added spatial regularization, and so, for non-zero signals, one is required to have at least one non-zero coefficient ...
In this work, we present novel adaptations of popular sparse coding algorithms that become better suited for solving large-scale problems by exploiting spatial-angular separability. ...
The other is from a signal processing perspective: maintain accurate signal reconstructions while devising methods to exploit redundancies in the 20 data and reduce the number of required measurements ...
