Transferring Nonlinear Representations using Gaussian Processes with a Shared Latent Space 

Urtasun, Raquel; Quattoni, Ariadna; Lawrence, Neil; Darrell, Trevor (2008-04-11)
When a series of problems are related, representations derived from learning earlier tasks may be useful in solving later problems. In this paper we propose a novel approach to transfer learning with low-dimensional, ...

Range Segmentation Using Visibility Constraints 

Taycher, Leonid; Darrell, Trevor (2001-09-01)
Visibility constraints can aid the segmentation of foreground objects observed with multiple range images. In our approach, points are defined as foreground if they can be determined to occlude some {em empty space} in the ...

Inferring 3D Structure with a Statistical Image-Based Shape Model 

Grauman, Kristen; Shakhnarovich, Gregory; Darrell, Trevor (2003-04-17)
We present an image-based approach to infer 3D structure parameters using a probabilistic "shape+structure'' model. The 3D shape of a class of objects may be represented by sets of contours from silhouette views ...

Efficient Image Matching with Distributions of Local Invariant Features 

Grauman, Kristen; Darrell, Trevor (2004-11-22)
Sets of local features that are invariant to common image transformations are an effective representation to use when comparing images; current methods typically judge feature sets' similarity via a voting scheme (which ...

Pyramid Match Kernels: Discriminative Classification with Sets of Image Features (version 2) 

Grauman, Kristen; Darrell, Trevor (2006-03-18)
Discriminative learning is challenging when examples are sets of features, and the sets vary in cardinality and lack any sort of meaningful ordering. Kernel-based classification methods can learn complex decision boundaries, ...

Discriminative Gaussian Process Latent Variable Model for Classification 

Urtasun, Raquel; Darrell, Trevor (2007-03-28)
Supervised learning is difficult with high dimensional input spacesand very small training sets, but accurate classification may bepossible if the data lie on a low-dimensional manifold. GaussianProcess Latent Variable ...

Latent-Dynamic Discriminative Models for Continuous Gesture Recognition 

Morency, Louis-Philippe; Quattoni, Ariadna; Darrell, Trevor (2007-01-07)
Many problems in vision involve the prediction of a class label for each frame in an unsegmented sequence. In this paper we develop a discriminative framework for simultaneous sequence segmentation and labeling which can ...

Transfering Nonlinear Representations using Gaussian Processes with a Shared Latent Space 

Urtasun, Raquel; Quattoni, Ariadna; Darrell, Trevor (2007-11-06)
When a series of problems are related, representations derived fromlearning earlier tasks may be useful in solving later problems. Inthis paper we propose a novel approach to transfer learning withlow-dimensional, non-linear ...

Approximate Correspondences in High Dimensions 

Grauman, Kristen; Darrell, Trevor (2006-06-15)
Pyramid intersection is an efficient method for computing an approximate partial matching between two sets of feature vectors. We introduce a novel pyramid embedding based on a hierarchy of non-uniformly shaped bins that ...
