Conference on Visual Information Processing III

In this paper rank filters of adaptive length are presented. The filtering objective of these filters is the suppression of impulsive noise while preserving as much image detail as possible, and also high computational efficiency. In the proposed scheme the window size and shape are adaptively adjusted based on the amount of impulsive noise in an initial starting window. Using smaller windows increases the computational efficiency. To further improve the computational efficiency, median data blocks are used. The loss of image detail is prevented by an adaptive algorithm. Filtering examples demonstrating noise suppression, detail preservation, and computational efficiency are presented.

A distributed parameter estimation algorithm is presented for a general nonlinear measurement model with additive Gaussian noise. We show that the Bayes-closed estimation algorithm developed by Kulhavy, when extended to the multisensor case leads to a linear fusion rule, regardless of the form of a local a posteriori densities. Specifically, the Kulhavy algorithm generates a set of reduced sufficient statistics representing the local sensor densities, which are simply added and subtracted at the global processor to obtain optimum fusion. We discuss various approximations to the Bayes-closed algorithm which leads to a practical parameter estimator for the nonlinear measurement model, and apply such an approximate technique to the bearings-only tracking problem. The performance of the distributed tracker is compared to an alternative algorithm based on the extended Kalman filter (EKF) implemented in modified polar coordinates. It is shown that the Bayes-closed estimator does not diverge in the sense of an ordinary EKF, and hence the Bayes-closed technique can be employed in both a unidirectional and bidirectional transmission mode.

Synthetic estimation filters (SEFs) have been found useful for the determination of distortion parameters, such as angle of rotation of objects from their images. Previous SEFs, designed using matched and phase only filters required a knowledge of exact location of the object to produce a reasonable accuracy of estimation. To overcome the limitation, use of MACE filters is proposed for the construction of synthetic estimation filters. As the MACE filters are designed to have their peaks at the origin of the correlation plane, detection of the peak can be done without a knowledge of the exact position of the object. Computer simulations are used to study the performance of MACE-SEFs. It is found that significant errors result at rotation angle which are not part of the training set. An improved linearity leading to an increase in accuracy was realized when the MINCE concept was used in place of the MACE concept for the design of the SEFs.

Conference on algorithms for Synthetic Aperture Radar Imagery

作者： SHAW, SW SRI INT MENLO PKCA 94025

ISBN: (纸本)0819415340

Ultrawideband (UWB) SAR images often contain clutter and other types of spatially correlated noise. To reduce these effects, we have developed a complex, multichannel, autoregressive image- modeling and inverse-filtering algorithm. Our algorithm extends a previously reported technique to include complex image data and a solution to the directionality problem of 2D AR models. A multichannel image pixel, represented by a vector, is modeled as an autoregressive process with a nonsymmetric half-plane (NSHP) support region. The parameters of this NSHP AR model, represented as matrices, are estimated by minimizing a squared residual. To account for possible nonstationarity in the image statistics, the estimation is performed over a series of small subwindows, which lends a degree of adaptabtility to the algorithm. Once estimates of the complex AR parameter matrices are obtained, they are used in an inverse filter. To account for the directionality inherent in the NSHP filter, we have adopted a bi-directional filtering approach, with the results of the two filters combined such that targets are enhanced and clutter is minimized. This algorithm has been applied to various UWB SAR images and shown to be an effective whitening filter. The resulting signal-to-clutter enhancement depends on a variety of factors, including clutter statistics, target size, and AR model order. A version of the whitening algorithm has been incorporated into our standard set of tools for processing UWB SAR images.

Worldwide there are many different scripts and languages in common use. Finding text lines and character and word boundaries, where present, are necessary primitive operations for most document processing applications. We have developed a method of handling text lines from several different languages that is robust in the presence of common printing and scanning artifacts. A technique is described by which information about the characteristics of a text line can be determined from a list of the connected pixel components that comprise the image. This technique applies across many languages and scripts that are laid out horizontally. For text comprising Roman type, the location and dimensions of each text line are augmented with positions of the baseline and x-height. Where appropriate, coordinates of space-delimited words and individual character cells are determined. This technique incorporates a computationally inexpensive method for straightening curved lines and segmenting kerned characters and a novel method based on font weight and stress for locating the boundaries of individual characters, even if their images touch.

This paper presents a new multiscale edge detection algorithm. The algorithm is based on a new nonlinear filter, which produces a scale-space filtering analogous to Gaussian filtering but has several interesting properties such as viewpoint invariance and automatic edge preservation. From this multiscale representation, the algorithm uses a multidimensional morphological operator to compute the position of edges. A mathematical analysis of the algorithm and its efficient software implementation is discussed. Experimental results illustrating the use of the filter to detect multiscale depth and orientation discontinuities on range images and significant edges on intensity images are also presented.

A basic class of structuring-element pairs for segmentation-free character recognition via the morphological hit-or-miss transform is developed for Courier font. Both hit and miss structuring elements are sparse and they are selected so that the hit-or-miss transform can be applied across the test image without prior segmentation. Besides being able to achieve high rates of accuracy on text with touching characters, the hit-or-miss algorithm, as developed herein, is shown to be very robust with respect to the threshold level for the input gray-scale data.

The design of hybrid transmission algorithms for the multiplexing of voice and data over a common digital channel is of interest to various communication networks, including cellular radio and high speed topologies. In environments where the characteristics of the voice and data traffics may vary dynamically, the issue is the deployment of Hybrid Multiplexing algorithms (HMAs) which satisfy the constraints imposed by the voice traffic, while they simultaneously attain high channel utilization and induce low implementation overhead. In this work, we propose, evaluate, and compare two HMAs: a semidynamic and a dynamic. The former induces lower implementation overhead than the latter, but it is applicable only to environments where the rate of the voice traffic may vary relatively slowly and its statistics are parametrically known. The semidynamic HMA induces frame structures, where the capacity allocation per frame, for the voice versus data traffic, is dictated by a superimposed traffic monitoring algorithm. The dynamic HMA, on the other hand, assigns each channel slot to voice versus data packets dynamically; it requires no statistical knowledge about the voice traffic, at the expense of significantly increased implementation overhead.

The paper describes how, given a ridge-and-valley image of a fingerprint, a flow map can be extracted. The first step is a unique grayscale algorithm based on 3D mathematical morphology to extract the ridge lines under a wide range of conditions. The paper then compares the results of finding the ridge flow using micropatterns, extended templates (on binary and grayscale images), and several well-known, traditional techniques. The question of spatial resolution is also addressed.

Individual cluster validation has not received as much attention as partition validation. This paper presents two measures for evaluating individual clusters in a fuzzy partition. They both account for properties of the fuzzy memberships as well as the structure of the data. The first measure is a ratio between compactness and separation of the fuzzy clusters; the second is based on counting a contradiction between properties of the fuzzy memberships and the stucture of the data. These two measures are applied and compared in evaluating fuzzy clusters generated by the fuzzy c-means algorithm for segmentation of magnetic resonance images of the brain.
