Constrained Restoration and the Recovery of Discontinuities
The linear image restoration problem is to recover an original brightness distribution X/sup0/ given the blurred and noisy observations Y=KX/sup 0/+B, where K and B represent the point spread function and measurement error, respectively. Expand

  • 1 October 1997
We explore a new approach to shape recognition based on a virtually infinite family of binary features (queries) of the image data, designed to accommodate prior information about shape invariance and regularity. Expand

Nonlinear image recovery with half-quadratic regularization
We use an auxiliary array and an extended objective function in which the original variables appear quadratically and the auxiliary variables are decoupled. Expand
