Abstract

The authors have proposed a novel depth from defocus (DFD) technique based on a cross reblurring approach. While the technique gives a precise depth estimation, it is unfortunately affected by a disalignment of pixels in a set of multi-focus images. This paper thus proposes a compensation technique for the disalignment to reduce the estimation error. The experimental results given in this paper provide the validity of our approach.
