The contributions of automatic semantic concept classifiers for interactive filtering (classifiers in conjunction with query rankings) and browsing (classifiers in lieu of query rankings) are tested against three test corpora: an amateur photo collection, documentary video, and news video. Results show that current classifiers offer browsing utility twice as good as having no classifier at all, and that continuous improvements in the classifiers produce comparable improvements in the browsing utility. For filtering a wellordered set of results (e.g., a set retrieved from text search), concept classifiers need greater accuracy: current classifiers showed worse performance than not filtering at all, even when the classifiers’ accuracy is nearly doubled. Results are consistent for all test corpora. Hence, automatic semantic concepts can offer significant utility for browsing at current levels of accuracy, but the requirement is much higher for filtering a well-ordered set of results, where extreme accuracy is necessary before benefits are seen.

A Graph Based Approach for Naming Faces in News Photos

A Graph Based Approach for Naming Faces in News Photos

conference on computer vision and pattern recognition (CVPR)

作者： D. Ozkan P. Duygulu Department of Computer Engineering Bilkent University Ankara Turkey

We propose a method to associate names and faces for querying people in large news photo collections. On the assumption that a person’s face is likely to appear when his/her name is mentioned in the caption, first all the faces associated with the query name are selected. Among these faces, there could be many faces corresponding to the queried person in different conditions, poses and times, but there could also be other faces corresponding to other people in the caption or some non-face images due to the errors in the face detection method used. However, in most cases, the number of corresponding faces of the queried person will be large, and these faces will be more similar to each other than to others. In this study, we propose a graph based method to find the most similar subset among the set of possible faces associated with the query name, where the most similar subset is likely to correspond to the faces of the queried person. When the similarity of faces are represented in a graph structure, the set of most similar faces will be the densest component in the graph. We represent the similarity of faces using SIFT descriptors. The matching interest points on two faces are decided after the application of two constraints, namely the geometrical constraint and the unique match constraint. The average distance of the matching points are used to construct the similarity graph. The most similar set of faces is then found based on a greedy densest component algorithm. The experiments are performed on thousands of news photographs taken in real life conditions and, therefore, having a large variety of poses, illuminations and expressions.

We propose a novel, fast and robust technique for the computation of anatomical connectivity in the brain. Our approach exploits the information provided by Diffusion Tensor Magnetic Resonance Imaging (or DTI) and models the white matter by using Riemannian geometry and control theory. We show that it is possible, from a region of interest, to compute the geodesic distance to any other point and the associated optimal vector field. The latter can be used to trace shortest paths coinciding with neural fiber bundles. We also demonstrate that no explicit computation of those 3D curves is necessary to assess the degree of connectivity of the region of interest with the rest of the brain. We finally introduce a general local connectivity measure whose statistics along the optimal paths may be used to evaluate the degree of connectivity of any pair of voxels. All those quantities can be computed simultaneously in a Fast Marching framework, directly yielding the connectivity maps. Apart from being extremely fast, this method has other advantages such as the strict respect of the convoluted geometry of white matter, the fact that it is parameter-free, and its robustness to noise. We illustrate our technique by showing results on real and synthetic datasets. OurGCM(Geodesic Connectivity Mapping) algorithm is implemented in C++ and will be soon available on the web.

Fast Compact City Modeling for Navigation Pre-Visualization

Fast Compact City Modeling for Navigation Pre-Visualization

作者： N. Cornelis K. Cornelis L. Van Gool Katholieke Universiteit Leuven Heverlee Belgium

Nowadays, GPS-based car navigation systems mainly use speech and aerial views of simplified road maps to guide drivers to their destination. However, drivers often experience difficulties in linking the simple 2D aerial map with the visual impression that they get from the real environment, which is inherently ground-level based. Therefore, supplying realistically textured 3D city models at ground-level proves very useful for pre-visualizing an upcoming traffic situation. Because this pre-visualization can be rendered from the expected future viewpoints of the driver, the latter will more easily understand the required maneuver. 3D city models can be reconstructed from the imagery recorded by surveying vehicles. The vastness of image material gathered by these vehicles, however, puts extreme demands on vision algorithms to ensure their practical usability. Algorithms need to be as fast as possible and should result in compact, memory efficient 3D city models for future ease of distribution and visualization. For the considered application, these are not contradictory demands. Simplified geometry assumptions can speed up vision algorithms while automatically guaranteeing compact geometry models. We present a novel city modeling framework which builds upon this philosophy to create 3D content at high speed which could allow for pre-visualization of any conceivable traffic situation by car navigation modules.

Gesture recognition using Hidden Markov Models from Fragmented Observations

Gesture Recognition using Hidden Markov Models from Fragment...

conference on computer vision and pattern recognition (CVPR)

作者： Ruiduo Yang S. Sarkar Computer Science and Engineering Department University of South Florida Tampa FL USA

We consider the problem of computing the likelihood of a gesture from regular, unaided video sequences, without relying on perfect segmentation of the scene. Instead of requiring that low-and mid-level processes produce near-perfect segmentation of relevant body parts such as hands, we take into account that such processes can only produce uncertain information. The hands can only be detected as fragmented regions along with clutter. To address this problem, we propose an extension of the HMM formalism, which we call the frag-HMM, to allow for reasoning based on fragmented observations, via the use of an intermediate grouping process. In this formulation, we do not match the frag- HMMto one observation sequence, but rather to a sequence of observation sets, where each observation set is a collection of groups of fragmented observations. Based on the developed model, we show how to perform three kinds of computations. The first one is to decide on the best observation group for each frame, given a sequence of observation groups for the past frames. This allows us to incrementally compute the best segmentation of the hand for each frame, given the model. The second one involves the computation of likelihood of a sequence, averaged over all possible states sequences and possible groupings. The third is the computation of the likelihood of a sequence, maximized over all possible state sequences and group sequences. This can give us the best possible groupings for each frame, as well. We demonstrate our ideas using a publicly available hand gesture dataset that spans different subjects, is against complex background, and involves hand occlusions. The recognition performance is within 2% of that obtained with manually segmented hands and about 10% better than that obtained with segmentations that use the prior knowledge of the hand color.

Kernel Discriminant Analysis (KDA) has been shown to be one of the promising approaches to handle the pose and illumination problem in face recognition. However, empirical results show that the performance for KDA on face recognition is sensitive to the kernel function and its parameters. Instead of following existing KDA methods in selecting popular kernel function, this paper proposes a new approach for constructing kernel using wavelet. By virtue of cubic B spline function, wavelet kernel function is constructed. A wavelet kernel based subspace linear discriminant (WKSLDA) algorithm is then developed for face recognition. Two human face databases, namely FERET and CMU PIE databases, are selected for evaluation. The results are encouraging. Comparing with the existing state-of-the-art RBF kernel based LDA methods, the proposed method gives superior resu

Moving Object Segmentation using Scene Understanding

Moving Object Segmentation using Scene Understanding

ieee computer society conference on computer vision and pattern recognition Workshops (CVPRW)

作者： A.G.A. Perera G. Brooksby A. Hoogs G. Doretto GE Global Research Center Niskayuna NY USA

We present a novel approach to moving object detection in video taken from a translating, rotating and zooming sensor, with a focus on detecting very small objects in as few frames as possible. The primary innovation is to incorporate automatically computed scene understanding of the video directly into the motion segmentation process. Scene understanding provides spatial and semantic context that is used to improve frame-to-frame homography computation, as well as direct reduction of false alarms. The method can be applied to virtually any motion segmentation algorithm, and we explore its utility for three: frame differencing, tensor voting, and generalized PCA. The approach is especially effective on sequences with large scene depth and much parallax, as often occurs when the sensor is close to the scene. In one difficult sequence, our results show an 8-fold reduction of false positives on average, with essentially no impact on the true positive rate. We also show how scene understanding can be used to increase the accuracy of frame-to-frame homography estimates.

We address the multi-view shape from shading problem, that is the recovery of 3-D shape, lighting configuration and surface albedo from multiple calibrated views. Previous approaches to this problem relied on physically impossible illumination models (negative light) and only work on constant albedo and resulted in biased estimates of shape and lighting positions. Furthermore, since the solution involves infinite-dimensional optimization, existing approaches were quite slow. We develop a new model that explicitly enforces positivity in the light sources with the assumption that the object is Lambertian and its albedo is piecewise constant and show that the new model significantly improves the accuracy and robustness relative to existing approaches. Furthermore, we show that the most computationally expensive step in the optimization can actually be solved in closed form. This significantly improves speed of convergence over existing schemes. We illustrate the behavior of our algorithm directly on the same data used by previous authors, so direct comparison is possible.

作者： Liya Ding A.M. Martinez Department of Electrical and Computer Engineering Ohio State Uinversity USA

The design of systems that can analyze and recognize American Sign Language (ASL) sentences, require that motion patterns and handshapes be independently represented from one another. In this paper, we define an algorithm that first obtains the 3D shape of each of the linguistically significant fingers (known as "selected" fingers in the linguistic literature), and then represents the motion of the hand as a three-dimensional trajectory in the coordinate system of the camera. In doing so, we address the problems caused by self-occlusions and localization errors. The 3D shape is obtained using an affine structure from motion algorithm that is based on the linear fitting of matrices with missing data. To recover the 3D motion of the hand, we define a robust algorithm that selects the most stable solution from the pool of all the solutions given by the three point resection problem. To be robust to localization errors (of the hand feature points tracked) we define a simple algorithm that searches for that combination of coordinates that gives the largest number of stable solutions in our system of equations. To validate our theory, we provide a set of experimental results using video sequences of ASL signs.

In most of computational anatomy studies, pose is disregarded because pose information mainly depends on non relevant external factors. However, the relative pose among different objects belonging to a complex multi-object system may be useful for diagnosis, prognosis and monitoring. In this work a methodology to build statistical multi-object pose models (MOPM) is described. The methodology is based on Principal Geodesic Analysis because the space of similarity transformations does not form a vector space. Methods to compute statistics, namely averages and variation modes, are described in detail. Experimental results are performed on neuroanatomical structures such as the subcortical nuclei (caudate nucleus, hippocampus, amygdala, thalamus, putamen, pallidum) and lateral ventricles. We expect that multi-object pose models will be useful as a valuable a priori information about relative location, orientation and scale of each structure. This compact model will be relevant as a coarse initialization for segmentation, or regularization of segmentation and registration algorithms.
