This process is experimental and the keywords may be updated as the learning algorithm improves.ĭ. These keywords were added by machine and not by the authors. This necessitates the implementation method to update the image in such a manner that the update points always lie in the subset of the image space where both the properties are satisfied. If the step sizes are not appropriately chosen, then the four-point property is not satisfied for all points in the image space. In this case, the AM algorithm converges to the infimum. It is further proved that with a proper choice of image and PSF step sizes and in the presence of sufficient regularization, the four-point property is satisfied for all points in the image space. We show that the three-point property is satisfied for all points in the image space and derive the non-negative function needed for the definition of three- and four-point properties. The analysis proceeds by looking at the reduction in the cost function when one variable is kept constant and the other is minimized. We use the three-point and four-point properties for proving that the AM algorithm for blind deconvolution converges to the infimum of the cost function. Hence we consider spatial domain convergence analysis in this chapter. Fourier domain analysis is feasible only for regularizers that are quadratic in nature.
