Learning to Efficiently Detect Repeatable Interest Points in Depth Data
Interest point (IP) detection is an important component of many computer vision methods. While there are a number of methods for detecting IPs in RGB images, modalities such as depth images and range scans hav...

Indoor Segmentation and Support Inference from RGBD Images
We present an approach to interpret the major surfaces, objects, and support relations of an indoor scene from an RGBD image. Most existing work ignores physical interactions or is applied only to tidy rooms a...

A Convex Discrete-Continuous Approach for Markov Random Fields
We propose an extension of the well-known LP relaxation for Markov random fields to explicitly allow continuous label spaces. Unlike conventional continuous formulations of labelling problems which assume that...

Large-Lexicon Attribute-Consistent Text Recognition in Natural Images
This paper proposes a new model for the task of word recognition in natural images that simultaneously models visual and lexicon consistency of words in a single probabilistic model. Our approach combines loca...

Latent Hough Transform for Object Detection
Hough transform based methods for object detection work by allowing image features to vote for the location of the object. While this representation allows for parts observed in different training instances to...

Energy Minimization under Constraints on Label Counts
Many computer vision problems such as object segmentation or reconstruction can be formulated in terms of labeling a set of pixels or voxels. In certain scenarios, we may know the number of pixels or voxels wh...

TriangleFlow: Optical Flow with Triangulation-Based Higher-Order Likelihoods
We use a simple yet powerful higher-order conditional random field (CRF) to model optical flow. It consists of a standard photo-consistency cost and a prior on affine motions both modeled in terms of higher-or...

Geometric Image Parsing in Man-Made Environments
We present a new parsing framework for the line-based geometric analysis of a single image coming from a man-made environment. This parsing framework models the scene as a composition of geometric primitives s...

Graph Cut Based Inference with Co-occurrence Statistics
Markov and Conditional random fields (crfs) used in computer vision typically model only local interactions between variables, as this is computationally tractable. In this paper we consider a class of global pot...
