Multi-view image coding benefits from knowledge of the depicted scene's 3D geometry. To exploit geometry information for compression, two different approaches can be distinguished. In texture-based coding, images are converted to texture maps prior to compression. In image-based predictive coding, geometry is used for disparity compensation and occlusion detection between images. Coding performance of both approaches depends on the accuracy ...

Vertical guidance for an instrument approach to landing during conditions of reduced visibility is a crucial element with respect to safety of flight. It is noteworthy that this vertical component, to be most useful and safe, must desirably provide the pilot with no more than several feet of uncertainty. Unfortunately with GPS the vertical portion of the position information supplied to the pilot by GPS signals is the least precise because of the geometries involved. Many aspects of the contemporary UHF glide slope have been studied during its half century of use. This paper reports on advances that make it realistic to claim that a glide slope can be sited for Category I operation at any runway that meets the physical requirements for this type of operation. For the UHF glide slope, siting imperfections are accommodated by using one of five available types of contemporary glide slope systems or derivatives thereof. This paper reviews how accommodations are achieved in practical cases.
A new metric, the spherical equivalent vulnerability radius (SEVR), for evaluating the low probability of detection (LPD) attributes of emitting systems is developed and proposed. The metric extends the classical CEVR to three dimensions. The SEVR is defined as the radius of an equivalent sphere defined by the actual detection volume around a receiver given a desired level of vulnerability. The extension makes possible a vulnerability assessment of emitting platforms capable of maneuvering in up to six-degrees-of-freedom (e.g. aircraft) while accounting for ground, airborne, and space borne threats operating in arbitrary geometries with respect to the emitter. We demonstrate how to evaluate the LPD performance using the SEVR and its value as a single parameter summary statistic versus classic CEVR in a test case scenario. As is shown, the primary factors affecting the SEVR are the spatial selectivity of the emitting system antenna and the threat interceptors' sensitivity. A major benefit of the SEVR is eliminating explicit intercept geometry from the evaluation. Of particular interest is the application of SEVR in the design and evaluation of communications antennas for stealth aircraft, as well as in mission planning.
This contribution concerns the retrieval of colour texture. The interband correlation structure is considered by modeling the heavy-tailed image wavelet histograms with a multivariate generalized Gaussian. As a similarity measure we propose to use the Rao geodesic distance, which, in contrast to the Kullback-Leibler divergence, exists in a closed form for any fixed value of the shape pa rameter of the distribution. We apply this in several retrieval experiments. The modeling of the interband correlation significantly increases retrieval rates, while the geodesic distance is shown to outperform the Kullback- Leibler divergence. A multivariate Laplace distribution yields better results than a Gaussian, indicating the potential of a model with variable shape parameter together with the geodesic distance.
Multi-view image coding benefits from knowledge of the depicted scene's 3D geometry. To exploit geometry information for compression, two different approaches can be distinguished. In texture-based coding, images are converted to texture maps prior to compression. In image-based predictive coding, geometry is used for disparity compensation and occlusion detection between images. Coding performance of both approaches depends on the accuracy of the available geometry model. Texture-based and image-based coding are compared with regard to the influence of geometry accuracy on coding efficiency. The results are theoretically explained. Experiments with natural as well as synthetic image sets show that texture-based coding is more sensitive to small geometry inaccuracies than image-based coding. For approximate geometry models, image-based coding performs best, while texture-based coding yields superior coding results if scene geometry is exactly known.
The problem of document classification considers categorizing or grouping of various document types. Each document can be represented as a bag of words, which has no straightforward Euclidean representation. Relative word counts form the basis for similarity metrics among documents. Endowing the vector of term frequencies with a Euclidean metric has no obvious straightforward justification. A more appropriate assumption commonly used is that the data lies on a statistical manifold, or a manifold of probabilistic generative models. In this paper, we propose calculating a low-dimensional, information based embedding of documents into Euclidean space. One component of our approach motivated by information geometry is the Fisher information distance to define similarities between documents. The other component is the calculation of the Fisher metric over a lower dimensional statistical manifold estimated in a nonparametric fashion from the data. We demonstrate that in the classification task, this information driven embedding outperforms both a standard PCA embedding and other Euclidean embeddings of the term frequency vector.
This correspondence deals with the problem of designing planar shapes for subpixel image registration. Basic theoretical considerations are shown to lead to a lower bound on location accuracy. Optimal registration marks achieving this bound are discussed. These optimal designs, however, require very high printing or etching resolution and are inherently very sensitive to variations in the image sampling model (like scaling of grid size and rotation). More robust, optimal and suboptimal "topology-preserving" registration marks are then introduced and analyzed.
This paper presents an original data-hiding application where the payload is intimately related to the host data. On the other hand, we want to preserve this relationship so that each part of the payload is hidden in the related part of the host. On the other hand, we want to ensure that a degradation of the host data implies a proportional degradation of the related part of the hidden data.
Computerized ionospheric tomography (CIT) is an emerging technique that produces two and three-dimensional images of the electron distributions in the ionosphere. The limiting factor for CIT reconstructions is the inability to accurately estimate their vertical profiles due to the geometry of the CIT systems, which limits the amount of information detected at large projection angles. A relationship exists between the amount of information that is gathered at a particular projection angle, and the positions of the ground station receivers in the data acquisition system. The proper placement of these ground station receivers can increase the information content of the dataset, and consequently increase the resolution of the resulting images. In order to measure the effect of varying the placement of the ground station receivers, a resolution metric is needed. This paper presents a resolution measure based on projections that enables observation of the information content as a function of the ray path angle. This resolution measure can be used in the development of CIT systems as well as in the evaluation of existing system configurations.
With the development of signal processing technology, many new requirements are put forward for radar target detection. For instance, it should accurately detect the targets in perturbed environment and with small bunch of pulses. However, in the situation of a few number of pulses, the classical methods using coherent accumulation are not very satisfactory. In order to overcome the drawbacks, a lot of new mathematical methods were introduced. Information geometry method is one of these methods which researches statistical problems on the manifold and metric space, and it provides us a new method to enhance radar detection performance. Based on the method of information geometry and Constant False Alarm Rate (CFAR) detector, the paper introduces a new detection structure called Matrix Constant False Alarm Rate (MCFAR) DETECTOR to detect targets for Pulse Doppler radar with small bunch of pulses. The paper also simulates the feasibility of MCFAR DETECTOR and compare the performance with classical method. Results show that the MCFAR DETECTOR can accurately detect the targets and improve the detection performance.
The Fisher information matrix determines how much information is given by a measurement about the parameters that index the underlying probability distribution. This paper assumes that the parameters structure the mean value vector in a multivariate normal distribution. The Fisher matrix is then a Gramian constructed from the sensitivity vectors that characterize the first- order variation in the mean with respect to the parameters. The inverse of the Fisher matrix has several geometrical properties that bring insight into the problem of identifying multiple parameters. The angle between a given sensitivity vector and the linear subspace spanned by all others determines the variance bound for identifying a given parameter. Similarly, the covariance for identifying the linear influence of two different subsets of parameters depends on the principal angles between the linear subspaces spanned by the sensitivity vectors for the respective subsets.<<ETX>>
