Fast Multi-Focus Image Fusion Using Inner Channel Prior
In this paper, we propose a simple but effective sharpness prior—inner channel prior—to detect the focused area of multi-focus images. The inner channel prior is a kind of location feature of natural image sharpness.

Trade-Off Asymmetric Profile for Extended-Depth-of-Focus Ocular Lens
We explore the possibility of extending the depth of focus of an imaging lens with an asymmetric quartic phase-mask, while keeping the aberration within a relatively low level.

Extended Depth-of-Field of a Miniature Optical Endoscope Using Wavefront Coding
Endoscopic imaging is an indispensable tool for visual inspection of surfaces in hard-to-access places. The conventional optical endoscope only enables imaging the regions that lie close to the focal plane, and therefore improving the depth of field (DOF)
