Claim 17:
18. The method of claim 17, wherein
the obtained spatial basis includes a spatial basis matrix and the one or more temporal bases include a single temporal basis matrix;
the spatial basis matrix in combination with the temporal basis matrix represents a low-rank matrix corresponding to a collection of the plurality of time-series images; and
elements in the spatial basis matrix and the temporal basis matrix are fewer than elements in the low-rank matrix; and
wherein the reconstructing the target image based on the obtained spatial basis and the one or more temporal basis sub-sets includes:
reconstructing the target image by determining a product of the spatial basis matrix and the temporal basis sub-set of the single temporal basis matrix.
