Abstract

The restoration of an image modeled by piecewise-constant polygonal patches from its blurred (bandlimited) and noise corrupted version is considered. Under this model, the line-integral projections of the data image are piecewise linear signals, blurred and corrupted by noise. The break points and the associated amplitude parameters of each projection are estimated by minimizing the 1-D stochastic complexity of the projection using a recently proposed dynamic programming technique. The final image is reconstructed by convolution backprojection.
