Implementation of visual reconstruction networks-Alternatives to resistive networks

The resistive grid approach has been adopted by the Harris coupled depth-slope analog network and generalized for regularization involving arbitrary degrees of smoothness. The authors consider implementations of arbitrary order regularization networks which do not require resistive grids. The approach followed is to generalize the original formulation of J.G. Harris (1987) and then to follow alternative paths to analog circuit realization allowed by the generalization.<>
