Shape from focus is an elegant method that estimates the structure of a 3D object from a video of captured frames using the degree of focus as the principal cue. However, the quality of the estimated structure is vulnerable to scene texture. The effect is particularly pronounced for objects that are smooth relative to the magnification of the optical system. In this paper, the shape estimation process...
Traditional shape-from-focus (SFF) uses focus as the singular cue to derive the shape profile of a 3D object from a sequence of images. However, the stack of low-resolution (LR) observations is space-variantly blurred because of the finite depth of field of the camera. The authors propose to exploit the defocus information in the stack of LR images to obtain a super-resolved image as well as a high-resolution...
