Defocus map estimation from a single image via spectrum contrast.
TL;DR: The proposed method takes into consideration not only the affect of light refraction but also the blur texture of an image, and is more reliable in defocus map estimation compared to various state-of-the-art methods.
Journal ArticleDOI
Depth recovery and refinement from a single image using defocus cues
TL;DR: This method builds on the universal imaging principle: only scene at the focus distance will converge to a single sharp point on imaging sensor but other scene will yield different blur effects varying with its distance from the camera lens.
Journal ArticleDOI
Salient object detection using color spatial distribution and minimum spanning tree weight
TL;DR: This paper uses a segmentation algorithm to decompose an image into superpixel-level elements, then uses these elements as nodes to construct a minimum spanning tree (MST), each connected edge weight is the mean color difference between two nodes.
