Iterative reconstruction of space-limited scenes from noisy frequency-domain measurements

摘要: An iterative projection approach is introduced, which aims specifically at removing a priori information and constraint incompatibility due to noisy measurements. There soft frequency domain measurement proposed. The softness refers accepting an algorithm iterate whenever it "close enough" (depending on expected noise level) the scene limitation softened by providing smooth transition region between known extent zeroed regions of domain. operators involved are shown be nonexpansive, may naturally have many solutions, all compatible with information.
