Background Three main ingredients of action research are visual features, machine learning methodology, and datasets. Recent years have witnessed a tremendous increase in …
We present a method that takes as input a single dual-pixel image, and simultaneously estimates the image's defocus map---the amount of defocus blur at each pixel---and …
Smoothing and sharpening are two fundamental image processing operations. The latter is usually related to the former through the unsharp masking algorithm. In this paper, we …

This paper addresses the light field saliency detection problem via a multiple cue integration framework. By reinterpreting the usage of dark channels in estimating the amount of …
Shape from focus is an accurate, but relatively time-consuming, 3D profilometry technique (compared to eg, laser triangulation or fringe projection). This is the case because a large …
