Nonnegative Matrix Factorization with Earth Mover's Distance Metric for Image Analysis.

IEEE transactions on pattern analysis and machine intelligence

Sandler R, Lindenbaum M.
PMID: 21263163
IEEE Trans Pattern Anal Mach Intell. 2011 Aug;33(8):1590-602. doi: 10.1109/TPAMI.2011.18. Epub 2011 Jan 28.

Nonnegative matrix factorization (NMF) approximates a given data matrix as a product of two low-rank nonnegative matrices, usually by minimizing the L2 or the KL distance between the data matrix and the matrix product. This factorization was shown to...

IEEE transactions on pattern analysis and machine intelligence

Cui Y, Schuon S, Thrun S, Stricker D, Theobalt C.
PMID: 23520250
IEEE Trans Pattern Anal Mach Intell. 2013 May;35(5):1039-50. doi: 10.1109/TPAMI.2012.190.

We describe a method for 3D object scanning by aligning depth scans that were taken from around an object with a Time-of-Flight (ToF) camera. These ToF cameras can measure depth scans at video rate. Due to comparably simple technology,...

An incremental DPMM-based method for trajectory clustering, modeling, and retrieval.

IEEE transactions on pattern analysis and machine intelligence

Hu W, Li X, Tian G, Maybank S, Zhang Z.
PMID: 23520251
IEEE Trans Pattern Anal Mach Intell. 2013 May;35(5):1051-65. doi: 10.1109/TPAMI.2012.188.

Trajectory analysis is the basis for many applications, such as indexing of motion events in videos, activity recognition, and surveillance. In this paper, the Dirichlet process mixture model (DPMM) is applied to trajectory clustering, modeling, and retrieval. We propose...

Multiple Object Tracking Using K-Shortest Paths Optimization.

IEEE transactions on pattern analysis and machine intelligence

Berclaz J, Fleuret F, Türetken E, Fua P.
PMID: 21282851
IEEE Trans Pattern Anal Mach Intell. 2011 Sep;33(9):1806-19. doi: 10.1109/TPAMI.2011.21. Epub 2011 Feb 04.

Multi-object tracking can be achieved by detecting objects in individual frames and then linking detections across frames. Such an approach can be made very robust to the occasional detection failure: If an object is not detected in a frame...

Dynamic Refraction Stereo.

IEEE transactions on pattern analysis and machine intelligence

Morris NJ, Kutulakos KN.
PMID: 21282852
IEEE Trans Pattern Anal Mach Intell. 2011 Aug;33(8):1518-31. doi: 10.1109/TPAMI.2011.24. Epub 2011 Feb 04.

In this paper we consider the problem of reconstructing the 3D position and surface normal of points on an unknown, arbitrarily-shaped refractive surface. We show that two viewpoints are sufficient to solve this problem in the general case, even...

Active Learning Based on Locally Linear Reconstruction.

IEEE transactions on pattern analysis and machine intelligence

Zhang L, Chen C, Bu J, Cai D, He X, Huang TS.
PMID: 21282854
IEEE Trans Pattern Anal Mach Intell. 2011 Oct;33(10):2026-38. doi: 10.1109/TPAMI.2011.20. Epub 2011 Feb 04.

We consider the active learning problem, which aims to select the most representative points. Out of many existing active learning techniques, optimum experimental design (OED) has received considerable attention recently. The typical OED criteria minimize the variance of the...

Real-Time Head Pose Tracking with Online Face Template Reconstruction.

IEEE transactions on pattern analysis and machine intelligence

Li S, Ngan KN, Paramesran R, Sheng L.
PMID: 26584487
IEEE Trans Pattern Anal Mach Intell. 2016 Sep;38(9):1922-8. doi: 10.1109/TPAMI.2015.2500221. Epub 2015 Nov 12.

We propose a real-time method to accurately track the human head pose in the 3-dimensional (3D) world. Using a RGB-Depth camera, a face template is reconstructed by fitting a 3D morphable face model, and the head pose is determined...

Connected Filtering on Tree-Based Shape-Spaces.

IEEE transactions on pattern analysis and machine intelligence

Xu Y, Geraud T, Najman L.
PMID: 26415150
IEEE Trans Pattern Anal Mach Intell. 2016 Jun;38(6):1126-40. doi: 10.1109/TPAMI.2015.2441070. Epub 2015 Sep 22.

Connected filters are well-known for their good contour preservation property. A popular implementation strategy relies on tree-based image representations: for example, one can compute an attribute characterizing the connected component represented by each node of the tree and keep...

Fast Coding of Feature Vectors Using Neighbor-to-Neighbor Search.

IEEE transactions on pattern analysis and machine intelligence

Inoue N, Shinoda K.
PMID: 26415151
IEEE Trans Pattern Anal Mach Intell. 2016 Jun;38(6):1170-84. doi: 10.1109/TPAMI.2015.2481390. Epub 2015 Sep 23.

Searching for matches to high-dimensional vectors using hard/soft vector quantization is the most computationally expensive part of various computer vision algorithms including the bag of visual word (BoW). This paper proposes a fast computation method, Neighbor-to-Neighbor (NTN) search [1]...

Uncertain LDA: Including Observation Uncertainties in Discriminative Transforms.

IEEE transactions on pattern analysis and machine intelligence

Linear discriminant analysis (LDA) is a powerful technique in pattern recognition to reduce the dimensionality of data vectors. It maximizes discriminability by retaining only those directions that minimize the ratio of within-class and between-class variance. In this paper, using...

IEEE Trans Pattern Anal Mach Intell. 2016 Jun;38(6):1217-27. doi: 10.1109/TPAMI.2015.2478471. Epub 2015 Sep 14.

Typical feature selection methods choose an optimal global feature subset that is applied over all regions of the sample space. In contrast, in this paper we propose a novel localized feature selection (LFS) approach whereby each region of the...
