周波数領域におけるCross reblurring に基づく多焦点画像群からのdepth推定について

抄録

This paper proposes a frequency-domain realization of the depth from defocus(DFD) technique based on cross-reblurring, which is based on the property that two blurred images coincide if the others point spread functions is applied each other. The frequency domain approach can reduce the computation cost, which are demonstrated by the experimental results given later in the paper.
