Articulated models from video

Articulated models from video

conference on computer vision and pattern recognition (cvpr)

作者： N. Krahnstoever R. Sharma GE Research Schenectady NY USA Department of Computer Science and Engineering 220 Pond Laboratory Pennsylvania State University University Park PA USA

Past research on model-based tracking of articulated targets has neglected to address the problems of model-acquisition and initialization. However, for model-based approaches to ever become practical and autonomous, these important issues need to be addressed Towards this goal, this paper-presents a model-acquisition framework for acquiring articulated models directly from monocular video. Both structure, shape, and appearance of articulated models are estimated In addition, the initialization problem is solved by estimating pose information for at least one frame of a sequence, allowing subsequent model-based tracking. The presented work is based on basic assumptions and hence not restricted towards specific types of targets. It has in particular the ability to process human as well as non-human targets and makes no assumptions with respect to the structure of the kinematic tree or complexity. This work hence presents a set of systematic solutions to the problems of model-acquisition and initialization that bridge the gap between state of the art model-based tracking approaches and practical applications.

conference on computer vision and pattern recognition (cvpr)

作者： V. Athitsos J. Alon S. Sclaroff G. Kollios Computer Science Department Boston University Boston MA USA

This paper introduces BoostMap, a method that can significantly reduce retrieval time in image and video database systems that employ computationally expensive distance measures, metric or non-metric. Database and query objects are embedded into a Euclidean space, in which similarities can be rapidly measured using a weighted Manhattan distance. Embedding construction is formulated as a machine learning task, where AdaBoost is used to combine many simple, ID embeddings into a multidimensional embedding that preserves a significant amount of the proximity structure in the original space. Performance is evaluated in a hand pose estimation system, and a dynamic gesture recognition system, where the proposed method is used to retrieve approximate nearest neighbors under expensive image and video similarity measures: In both systems, in quantitative experiments, BoostMap significantly increases efficiency, with minimal losses in accuracy. Moreover, the experiments indicate that BoostMap compares favorably with existing embedding methods that have been employed in computer vision and database applications, i.e., FastMap and Bourgain embeddings.

Recovering shape and irradiance maps from rich dense texton fields

Recovering shape and irradiance maps from rich dense texton ...

conference on computer vision and pattern recognition (cvpr)

作者： A. Lobay D.A. Forsyth Computer Science Division University of California Berkeley Berkeley CA USA

We describe a method that recovers an estimate of surface shape and of the irradiance field for a textured surface. The method assumes the surface is viewed in scaled orthography, and we demonstrate the appropriateness of this assumption. Our method uses interest points to obtain the locations of putative texton instances, clusters the textons into types, and then uses an autocalibration method to recover the frontal appearance of each texton model. This yields (a) a dense set of normal estimates, each up to a two-fold ambiguity, (b) a dense set of irradiance estimates and (c) whether each instance is, in fact, an instance of the relevant texton. Because we are able to obtain a very large number of instances of a large number of different textons, this information is obtained at sites very closely spaced in the image. As a result, we need only a simple smoothness constraint to reconstruct a surface model, using EM to resolve the normal ambiguity. We show results on images of real scenes, comparing our reconstructions with those obtained using other methods and demonstrating the accuracy of both the recovered shape and the irradiance estimate.

Value directed learning of gestures and facial displays

Value directed learning of gestures and facial displays

conference on computer vision and pattern recognition (cvpr)

作者： J. Hoey J.J. Little Department of Computer Science University of British Columbia Vancouver BC Canada

This paper presents a method for learning decision theoretic models of facial expressions and gestures from video data. We consider that the meaning of a facial display or gesture to an observer is contained in its relationship to context, actions and outcomes. An agent wishing to capitalize on these relationships must distinguish facial displays and gestures according to how they help the agent to maximize utility. This paper demonstrates how an agent can learn relationships between unlabeled observations of a person's face and gestures, the context, and its own actions and utility function. The agent needs no prior knowledge about the number or the structure of the gestures and facial displays that are valuable to distinguish. The agent discovers classes of human non-verbal behaviors, as well as which are important for choosing actions that optimize over the utility of possible outcomes. This value-directed model learning allows an agent to focus resources on recognizing only those behaviors which are useful to distinguish. We show results in a simple gestural robotic control problem and in a simple card game played by two human players.

conference on computer vision and pattern recognition (cvpr)

作者： A. Gruber Y. Weiss School of Computer Science and Engineering Hebrew University of Jerusalem Jerusalem Israel

Multibody factorization algorithms give an elegant and simple solution to the problem of structure from motion even for scenes containing multiple independent motions. Despite this elegance, it is still quite difficult to apply these algorithms to arbitrary scenes. First, their performance deteriorates rapidly with increasing noise. Second, they cannot be applied unless all the points can be tracked in all the frames (as will rarely happen in real scenes). Third, they cannot incorporate prior knowledge on the structure or the motion of the objects. In this paper we present a multibody factorization algorithm that can handle arbitrary noise covariance for each feature as well as missing data. We show how to formulate the problem as one of factor analysis and derive an expectation-maximization based maximum-likelihood algorithm. One of the advantages of our formulation is that we can easily incorporate prior knowledge, including the assumption of temporal coherence. We show that this assumption greatly enhances the robustness of our algorithm and present results on challenging sequences.

A probabilistic framework for combining tracking algorithms

A probabilistic framework for combining tracking algorithms

引用

conference on computer vision and pattern recognition (cvpr)

作者： I. Leichter M. Lindenbaum E. Rivlin Department of Computer Science Technion-Israel Institute of Technology Haifa Israel

For the past few years researches have been investigating enhancing tracking performance by combining several different tracking algorithms. We propose an analytically justified, probabilistic framework to combine multiple tracking algorithms. The separate tracking algorithms considered output a probability distribution function of the tracked state, sequentially for each image. The algorithms may output either an explicit probability distribution function, or a sample-set of it via condensation. The proposed framework is general and allows the combination of any set of separate tracking algorithms of this kind, even on different state spaces of different dimensionality, under a few reasonable assumptions. In many of the investigated settings, our approach allows us to treat the separate tracking algorithms as "closed boxes ". In other words, only the state distributions in the input and output are needed for the combination process. The suggested framework was successfully tested using various state spaces and datasets.

Hierarchical decision making scheme for sports video categorisation with temporal post-processing

Hierarchical decision making scheme for sports video categor...

引用

conference on computer vision and pattern recognition (cvpr)

作者： E. Jaser J. Kittler W. Christmas Centre for Vision Speech and Signal Processing University of Surrey Guildford UK

The problem of automatic sports video classification is considered. We develop a multistage decision making system that is founded on the concept of cues, i.e. pieces of visual evidence, characteristic of certain categories of sports that are extracted from key frames. The main decision making mechanism is a decision tree which generate hypotheses concerning the semantics of the sports video content. The final stage of the decision making process is a hidden Markov model system which bridges the gap between the semantic content categorisation defined by the user and the actual visual content categories. The latter is often ambiguous, as the same visual content may be attributed to different sport categories, depending on the context. We demonstrate experimentally that the contextual post-processing of the decision tree outputs by HMMs significantly improves the performance of the sports video classification system.

Inference of multiple subspaces from high-dimensional data and application to multibody grouping

conference on computer vision and pattern recognition (cvpr)

作者： Zhimin Fan Jie Zhou Ying Wu Department of Automation Tsinghua University China Department of ECE Northwestern University IL USA

Multibody grouping is a representative of applying sub-space constraints in computer vision tasks. Under linear projection models, feature points of multibody reside in multiple subspaces. We formulate the problem of multi-body grouping as multiple subspace inference from high- dimensional data space. The theoretical value and practical advantage of this formulation come from the relaxation of the motion independency assumption, which has to be enforced in most factorization, based methods. In the proposed method, an oriented-frame (OF), which is a multi-dimensional coordinate frame, is associated with each data point indicating the point's preferred subspace structure. Then, a similarity measurement of these OFs is introduced and a novel mechanism is devised for conveying the information of the inherent subspace structure among the data points. In contrast to the existing factorization-based algorithms that cannot find correct segmentation of correlated motions such as articulated motion, the proposed method can robustly handle motion segmentation of both independent and correlated cases. Results on controlled and real experiments show the effectiveness of the proposed sub-space inference method.

conference on computer vision and pattern recognition (cvpr)

作者： M. Dimitrijevic S. Ilic P. Fua Computer Vision Laboratory Swiss Federal Institute of Technology Lausanne Switzerland

We propose a face reconstruction technique that produces models that not only look good when texture mapped, but are also metrically accurate. Our method is designed to work with short uncalibrated video or movie sequences, even when the lighting is poor resulting in specularities and shadows that complicate the algorithm's task. Our approach relies on optimizing the shape parameters of a sophisticated PCA based model given pairwise image correspondences as input. All that is required is enough relative motion between camera and subject so that we can derive structure from motion. By matching the results against laser scanning data, we will show that its precision is excellent and can be predicted as a junction of the number and quality of the correspondences. This is important if one wishes to obtain the appropriate compromise between processing speed and quality of the results. Furthermore, our method is in fact not specific to faces and could equally be applied to any shape for which a shape model controlled with relatively small number of parameters exists.

conference on computer vision and pattern recognition (cvpr)

作者： Yifan Shi Yan Huang D. Minnen A. Bobick I. Essa GVU Center & College of Computing Georgia Institute of Technology Atlanta GA USA

We present propagation networks (P-nets), a novel approach for representing and recognizing sequential activities that include parallel streams of action. We represent each activity using partially ordered intervals. Each interval is restricted by both temporal and logical constraints, including information about its duration and its temporal relationship with other intervals. P-nets associate one node with each temporal interval. Each node is triggered according to a probability density function that depends on the state of its parent nodes. Each node also has an associated observation function that characterizes supporting perceptual evidence. To facilitate real-time analysis, we introduce a particle filter framework to explore the conditional state space. We modify the original condensation algorithm to more efficiently sample a discrete state space (D-condensation). Experiments in the domain of blood glucose monitor calibration demonstrate both the representational power of P-nets and the effectiveness of the D-condensation algorithm.
