A novel depth estimation method using infocused and defocused images

摘要

The blur amount of an image changes proportional to scene depth. Depth from Defocus (DFD) is an approach in which a depth map can be obtained using blur amount calculation. In this paper, a novel DFD method is proposed in which depth is measured using an infocused and a defocused image. Subbaro's algorithm [4] is used as a preliminary depth estimation method and two complimentary approaches are provided to overcome drawbacks in edge and smooth areas1.
