Efficient Graph-Based Image Segmentation

TLDR
An efficient segmentation algorithm is developed based on a predicate for measuring the evidence for a boundary between two regions using a graph-based representation of the image and it is shown that although this algorithm makes greedy decisions it produces segmentations that satisfy global properties.
Abstract
This paper addresses the problem of segmenting an image into regions. We define a predicate for measuring the evidence for a boundary between two regions using a graph-based representation of the image. We then develop an efficient segmentation algorithm based on this predicate, and show that although this algorithm makes greedy decisions it produces segmentations that satisfy global properties. We apply the algorithm to image segmentation using two different kinds of local neighborhoods in constructing the graph, and illustrate the results with both real and synthetic images. The algorithm runs in time nearly linear in the number of graph edges and is also fast in practice. An important characteristic of the method is its ability to preserve detail in low-variability image regions while ignoring detail in high-variability regions.

Salient Object Detection via Structured Matrix Decomposition

TL;DR: A novel structured matrix decomposition model with two structural regularizations that captures the image structure and enforces patches from the same object to have similar saliency values, and a Laplacian regularization that enlarges the gaps between salient objects and the background in feature space is proposed.

Paper Doll Parsing: Retrieving Similar Styles to Parse Clothing Items

TL;DR: This paper tackles the clothing parsing problem using a retrieval based approach that combines parsing from: pre-trained global clothing models, local clothing models learned on the fly from retrieved examples, and transferred parse masks (paper doll item transfer) from retrieved example.

TL;DR: This work introduces group saliency to achieve superior unsupervised salient object segmentation by extracting salient objects (in collections of pre-filtered images) that maximize between-image similarities and within-image distinctness.

SceneNN: A Scene Meshes Dataset with aNNotations

TL;DR: This paper introduces SceneNN, an RGB-D scene dataset consisting of 100 scenes that is used as a benchmark to evaluate the state-of-the-art methods on relevant research problems such as intrinsic decomposition and shape completion.

The MediaMill TRECVID 2006 semantic video search engine

TL;DR: The MediaMill Challenge 2006 as discussed by the authors divided the generic video indexing problem into a visual-only, textual only, early fusion, late fusion, and combined analysis experiment and the MediaMill team participated in two tasks: concept detection and search.

Normalized cuts and image segmentation

TL;DR: This work treats image segmentation as a graph partitioning problem and proposes a novel global criterion, the normalized cut, for segmenting the graph, which measures both the total dissimilarity between the different groups as well as the total similarity within the groups.

Graph-Theoretical Methods for Detecting and Describing Gestalt Clusters

TL;DR: A family of graph-theoretical algorithms based on the minimal spanning tree are capable of detecting several kinds of cluster structure in arbitrary point sets; description of the detected clusters is possible in some cases by extensions of the method.
