Context-aware saliency detection
TLDR
A new type of saliency is proposed – context-aware saliency – which aims at detecting the image regions that represent the scene and a detection algorithm is presented which is based on four principles observed in the psychological literature.

What Makes a Patch Distinct?
TLDR
A novel and fast approach to compute pattern distinctness that relies on the inner statistics of the patches in the image for identifying unique patterns and outperforms all state-of-the-art methods on the five most commonly-used datasets.

Hierarchical mesh decomposition using fuzzy clustering and cuts
TLDR
A novel hierarchical mesh decomposition algorithm that computes a decomposition into the meaningful components of a given mesh, which generally refers to segmentation at regions of deep concavities and the utility of the algorithm in control-skeleton extraction is demonstrated.

How to Evaluate Foreground Maps
TLDR
This paper shows that the most commonly-used measures for evaluating both non-binary maps and binary maps do not always provide a reliable evaluation, and proposes a new measure that amends these flaws.

The Bloomier filter: an efficient data structure for static support lookup tables
TLDR
The Bloomier filter is introduced, a data structure for compactly encoding a function with static support in order to support approximate evaluation queries and lower bounds are provided to prove the (near) optimality of the constructions.

Mesh segmentation using feature point and core extraction
TLDR
A novel hierarchical mesh segmentation algorithm, which is based on new methods for prominent feature point and core extraction, which produces correct hierarchical segmentations of meshes, both in the coarse levels of the hierarchy and in the fine levels, where tiny segments are extracted.

Modeling by example
TLDR
This paper provides methods with which a user can search a large database of 3D meshes to find parts of interest, cut the desired parts out of the meshes with intelligent scissoring, and composite them together in different ways to form new objects.

Mesh Segmentation - A Comparative Study
TLDR
A comparative study of some of the latest algorithms and results in mesh segmentation, along several axes, sheds some light on the vital properties of the methods and on the challenges that future algorithms should face.

Surface Regions of Interest for Viewpoint Selection
TLDR
An algorithm for detecting the regions of interest of surfaces is proposed that looks for regions that are distinct both locally and globally and accounts for the distance to the foci of attention.

Metamorphosis of Polyhedral Surfaces using Decomposition
TLDR
A new algorithm for decomposing surfaces into patches based on their decompositions into patches is presented and a new projection scheme that handles topologically cylinder‐like polyhedral surfaces is presented.
