Inverse problem: comparison between linear back-projection algorithm and filtered back-projection algorithm in soft-field tomography

An image reconstruction algorithm in process tomography is very important in ensure that the reconstructed image is satisfied. The back-projection algorithm is the most popular algorithm applied in process tomography including a linear back-projection (LBP) algorithm and a filtered back-projection...
