Tomographic image reconstruction from limited-view projections with Wiener filtered focuss algorithm
14 years 8 months ago
In tomographic image reconstruction from limited-view projections the underlying inverse problem is ill-posed with the rank-deficient system matrix. The minimal-norm least squares...
