WebMar 27, 2013 · We introduce a novel dynamic imaging scheme, termed as blind compressive sensing (BCS), to improve the recovery of dynamic imaging datasets with large inter-frame motion. Similar to classical CS schemes [ 5 ]–[ 7 ], the voxel intensity profiles are modeled as a sparse linear combination of basis functions in a dictionary. WebIn this work, we focus on blind compressed sensing, where the underlying sparsifying transform is apriori unknown, and propose a framework to simultaneously reconstruct the underlying image as well as the sparsifying transform from highly undersampled measurements. ... multi-focus image and face recognition, (2) medical imaging like … WebThe feasibility of the BCS scheme was demonstrated for dynamic 3D free breathing MRI of lung volumes and diaphragm motion.
