Dictionary-based super resolution for positron emission tomography images

Dictionary-based super resolution for positron emission tomography images

In this paper, a strategy to increase the resolution of positron emission tomography (PET) images, using a previously trained high resolution dictionary for the sinograms is proposed. The low resolution input sinogram is divided into patches of 5x5 samples. The sparse code of each patch is calc...
