Removing blur from an image
TL;DR: In this paper, the Richardson-Lucy deconvolution process was used to deconvolve a selected image in the blurred image pyramid according to a bilateral range/spatial filter.
Patent
Textual attribute-based image categorization and search
Jian Sun,Litian Tao,Lu Yuan +2 more
TL;DR: In some aspects, images may be analyzed to identify a category of an image, or a portion thereof, and textual attributes may be associated with the image as mentioned in this paper, which can be used to replace or modify features of an existing target image.

Product Sparse Coding
Tiezheng Ge,Kaiming He,Jian Sun +2 more
TL;DR: This paper studies a special case of sparse coding in which the codebook is a Cartesian product of two subcodebooks, and presents algorithms to decompose this sparse coding problem into smaller subproblems, which can be separately solved.
Proceedings ArticleDOI
A geodesic-preserving method for image warping
TL;DR: This work proposes a geodesic-preserving method for content-aware image warping that is demonstrated in various applications, including rectangling panoramas, resizing panoramic/wide-angle images, and wide-angle image manipulation.
Journal ArticleDOI
Fuzzy Geodesics and Consistent Sparse Correspondences For: eformable Shapes
TL;DR: A new concept called fuzzy geodesics is presented and it is shown that fuzzy geodeics are stable with respect to the Gromov‐Hausdorff distance and a new object called the intersection configuration for a set of points on a shape is proposed.
