WebFeb 14, 2024 · In previous studies, CUP used a two-step iterative shrinkage/thresholding (TwIST) algorithm to reconstruct three-dimensional image information. However, the image reconstruction quality greatly depended on the selection of the penalty parameter, which caused the reconstructed images to be unable to be correctly determined if the ultrafast … WebThese approaches, such as conjugate gradient , iterative shrinkage/soft thresholding algorithm (ISTA) , two-step ISTA (TwIST) [21, 22], and fast iterative shrinkage/soft thresholding algorithm (FISTA) , have been investigated intensively in the literature.
