Paper Abstract

We proposed a new degradation model for auto focus blur between multiple objects with different out of focus parameters and the segmentation-based spatially adaptive regularized iterative restoration algorithm. In the proposed model, the boundary effect of out of focus objects is mathematically analyzed. By using experimental results, we show that the proposed restoration alignment can efficiently remove the space-variant out of focus blur of multiple blurred objects image.
