摘要:... The sparse characteristic of bioluminescent sources in spatial distribution has been widely explored in BLT and many L1-regularized methods have been investigated due to the sparsity-inducing properties of L1 norm. In this paper, we present a reconstruction method based on L1∕2...

摘要:... In this paper, we present a reconstruction method based on L 1 ∕ 2 regularization to enhance sparsity of BLT solution and solve the nonconvex L 1 ∕ 2 norm problem by converting it to a series of weighted L1 homotopy minimization problems with iteratively updated weights....
