CONF ON NONLINEAR image processing 2

作者： OLSTAD, B Norwegian Institute of Technology (Norway)

ISBN: (纸本)0819405507

An algorithm is presented for speckle reduction in time varying images. The algorithm operates in the time domain and is based on a subdivision of the time evolution of each pixel in the image into homogenous zones. The algorithm operates on a finite time window. The intensity evolution in this window is processed individually for each pixel in the image. The restored time evolution is defined as a piecewise linear function with a predefined maximal number of linear segments. The maximal number of segments is a parameter of the algorithm. Dynamic programming has been applied to obtain the piecewise linear function that minimizes the mean square error. For more than one segment the algorithm finds the optimal way to subdivide the time evolution into homogenous zones. Ordinary linear curve regression is used within each homogenous time segment. Several alternatives for temporal filtering based on discontinuity detection are discussed. The proposed algorithm reduces nonstationary speckle and increases the image contrast.

CONF ON VISUAL COMMUNICATIONS AND image processing 4

作者： WANG, TY LEE, CC Northwestern University (United States)

ISBN: (纸本)0819402389

This paper presents a very simple document recognition method called "segment coding". The method entails partitioning of a document into square segments of a given size and encode each segment according to the ratio of the numbers of black and white pixels inside the segment. The segment code is used as document feature for recognition. We show an experimental prototype which performs extremely well. We also show some analytical results including system parameter optimization and system performance versus database size. It is shown that the system is fast, flexible, extremely accurate and can accommodate a huge number of documents without significantly degrading recognition accuracy.

Contour fitting in image segmentation guarantees the closedness of the segment boundary at any stage of the approximation, thus preserving an important global property of the segment. A contour fitting scheme consists of strategies to modify the contour and to optimize the current approximation. For the purpose of contour modification a two-dimensional adaptation of a geometrically deformable model (GDM) is employed. A GDM is a polygon being placed into a structure to be segmented and being deformed until it adequately matches the segment's boundary. Deformation occurs by vertex translation and by introducing new vertices. Sufficient boundary resemblance is achieved by choosing vertex locations in such way that a function is optimized whose different terms describe features attributed to the segment or its boundary. In order to find ideal vertex locations, a stochastic optimisation method is applied which is able to avoid termination of the deformation process in a local optimum (caused, e.g., by noise or artefacts). The deformation terminates after segment boundary and GDM are sufficiently similar. Missing boundary parts between vertices are detected by a path searching technique in a graph whose nodes represent pixel locations. The segmentation algorithm was found to be versatile and robust in the presence of noise being able to segment artificial as well as real image data.

Conference on image and Video Communications and processing 2005

ISBN: (纸本)0819456586

In this paper we present an algorithm that segments a scanned, compound document into halftone and non-halftone areas. Our work is intended as a precursor to sophisticated document processing applications (descreening, compression, document content analysis, etc.) for which undetected halftones may cause serious adverse affects. Our method is of very low computational and memory complexity and performs only a single pass on the scanned document. Halftone regions of arbitrary size and shape are detected on compound multilingual documents in a completely automated fashion without any prior knowledge on the type and resolution of the halftones to be detected. The proposed technique can be adjusted to determine halftones of particular dpi resolution or decompose detected halftones to constituent resolutions. We obtain high detection probabilities on compound multilingual documents containing halftones and fine text.

The growth in text data available online is accompanied by a growth in the diversity of available documents. Corpora with extreme heterogeneity in terms of file formats, document organization, page layout, text style, and content are common. The absence of meaningful metadata describing the structure of online and open-source data leads to text extraction results that contain no information about document structure and are cluttered with page headers and footers, web navigation controls, advertisements, and other items that are typically considered noise. We describe an approach to document structure and metadata recovery that uses visual analysis of documents to infer the communicative intent of the author. Our algorithm identifies the components of documents such as titles, headings, and body content, based on their appearance. Because it operates on an image of a document, our technique can be applied to any type of document, including scanned images. Our approach to document structure recovery considers a finer-grained set of component types than prior approaches. In this initial work, we show that a machine learning approach to document structure recovery using a feature set based on the geometry and appearance of images of documents achieves a 60% greater F-1-score than a baseline random classifier.

algorithms and procedures employed to attain reliable and exhaustive segmentation in histopathologic imagery of colon and prostate sections are detailed. The algorithms are controlled and selectively called by a scene segmentation expert system as part of a machine vision system for the diagnostic interpretation of histopathologic sections. At this time, effective segmentation of scenes of glandular tissues is produced, with the system being conservative in the identification of glands; for the segmentation of overlapping glandular nuclei an overall success rate of approximately 90% has been achieved.

We register images based on their multiclass segmentations, for cases when correspondence of local features cannot be established. A discrete mutual information is used as a similarity criterion. It is evaluated at a sparse set of location on the interfaces between classes. A thin-plate spline regularization is approximated by pairwise interactions. The problem is cast into a discrete setting and solved efficiently by belief propagation. Further speedup and robustness is provided by a multiresolution framework. Preliminary experiments suggest that our method can provide similar registration quality to standard methods at a fraction of the computational cost.

The inspection and monitoring of the wear of grinding tools is essential to ensure the quality of the grinding tool surface and the finished product Most of the current methods for examining a grinding tool surface rely on dismounting the grinding tool. Often, the state of the grinding tool surface is checked indirectly by evaluating the quality of the workpiece. We describe the application of image processing, which offers an effective means for in situ inspection and monitoring. It yields more detailed information about the surface and the kind of wear observed than the common methods. By using multidirectional illumination and image fusion, an image with a high degree of relevant information is generated that is then segmented using the wavelet transform (multiscale analysis) and classified to distinguish grains and cavities on the surface. Results of the application of the algorithms for a high-performance grinding tool with CBN grains embedded in a resin base are presented. (C) 2004 SPIE and IST.

The objective of the paper is to present a new object based image coding technique using morphological segmentation. These are the first results of a final objective of proposing a completely new coding/decoding scheme for storage and transmission applications based on Mathematical Morphology. The paper presents a new object based image coding algorithm that involves three main processing steps: segmentation, coding of contours and coding of the inside. The three fundamental coding steps of our approach work on a multiscale representation of the data. The coding of contours represents the shape and location of the region and is based on techniques relying on chain codes. The coding of inside consists in modeling the gray level function of the image and in filling each region with this model. Orthogonal polynomials are used for inside coding and bit allocation techniques are developed such that efficient compression rates are obtained. Several computer generated images are presented that show good visual results for a variety of different compression ratios. The techniques can also be applied to image sequences. Current research is under way to propose new coding techniques for both the contour and the inside coding using Mathematical Morphology.
