"Integral Equation Models for Image Restoration: High Accuracy
Methods and Fast Algorithms"
Abstract: Discrete models are consistently used as practical models for
image restoration. They are piecewise constant approximations of the true
physical (continuous) model, and hence, inevitably impose bottleneck model
errors. We propose to work directly with the continuous model for image
restoration aiming at suppressing the model errors caused by the discrete
models. A systematic study is introduced in this talk for the continuous
out-of-focus image models which can be formulated as an integral equation
of the first kind. The resulting integral equation is regularized by the
Lavrentiev method and the Tikhonov method. We develop fast multiscale
algorithms having high accuracy to solve the regularized integral equations
of the second kind. Numerical experiments show that the methods based on
the continuous model perform much better than those based on discrete
models, in terms of PSNR values and visual quality of the reconstructed
images.
