This paper describes an approach for classifying OCR errors based on a new variation of a well-known dynamic programming algorithm. We present results from a large-scale experiment we performed involving the printing, scanning, and OCRing of over one million characters in each of three fonts. Times, Helvetica, and Courier. Our data allows us to draw a number of interesting conclusions about the nature of OCR errors for a particular font, as well as the relationship between error sets for different fonts.

Multisensor tracking and data fusion deals with combining data from various sources to arrive at an accurate assessment of the situation. Difficulties in performing multisensor tracking and fusion include not only ambiguous data, but also disparate data sources. In this paper, a software package called FUSEDAT which deals with tracking and data association with multiple sensors is described. FUSEDAT is implemented in the MATLAB environment and is portable to different platforms that support MATLAB. This software package provides a simple yet flexible environment for multitarget multisensor tracking and fusion. It is intended for rapid system prototyping and performance evaluation.

An important part of many algorithms that convert digital images of machine-printed text into their ASCII equivalent is information about fonts. This paper presents an algorithm for identifying the font in which a document is printed. The algorithm matches word-level information gathered from the document image to fonts in an image database. This method is more robust in the presence of noise than font recognition algorithms that use character-level information. Clusters of frequent function words (such as the, of, and, a, and to) are constructed from an input document image. The clusters are then matched to a database of function words derived from document images, and the document that matches best provides the identification of the input font. This technique utilizes the context from many words in an input document to overcome noise. Experimental results are presented that show near-perfect recognition of fonts, even in noisy documents.

To detect faint signals in the presence of a high background, differential techniques are often used. In IR astronomy this has led to the so-called chopping and nodding techniques. The introduction of array detectors especially for imaging in the thermal IR region of the astronomical spectrum requires an adaptations of these techniques which also takes into account the pixel nonuniformity of the array detector. I describe one possible imaging algorithm and the associated requirements for the chopping mechanisms of an 8-m telescope.

EXTRACTION OF 2D GROUPINGS FOR 3D OBJECT RECOGNITION 3

An approach for the recognition of 3D objects from single 2D views is presented. Using perceptual organization, hierarchies of features based on parallelism, co-linearity, and intersection are generated. Our local grouping algorithm is particularly inspired by the formalism defined by Etamadi et al., which is concerned with the formation of self-consistent groupings of straight lines from which all higher level groupings may be derived. Our approach extends this formalism to circular arcs. Surfaces in the scene are then extracted based on perceptual laws of symmetry and closure. The recognition process uses relational graphs of surfaces constructed by establishing the proximity, adjacency, and inclusion relations that exist between the surfaces. We identify closures which can be interpreted as the borders of the visible surfaces of objects and can also be used to describe the 2D shape of the surfaces. We show that a graph can be constructed from the relations between these closures and that similarities can be extracted from two different graphs obtained by analyzing two views of the same scene. Typical results obtained for complex indoor scenes are presented.

CONTOUR tracking OF 3D 26-CONNECTED DISCRETE OBJECTS

Conference on Image and Video Processing II

The goal of this paper is to introduce a surface tracking algorithm of 26-connected objects and to apply it to contour tracking of discrete 3D digital objects. We show that border notion is insufficient to make a distinction between outer points and points of its cavities. Then, we introduce 3D discrete surfaces modelization. A classical surface tracking algorithm is introduced for 6 and 18-connected objects. We propose an original contour tracking algorithm based on the surface tracking one, and an extension to 26-connected objects. Two parallelization strategies of the contour extraction algorithm are then proposed, one using a data structure of list, the other one, a spatial distribution of the image over the processors.

Word recognition using ideal word patterns

Word recognition using ideal word patterns

Document Recognition

作者： Zhao, Xin Srihari, Sargur N. SUNY/Buffalo (United States)

ISBN: (纸本)081941476X

The word shape analysis approach to text recognition is motivated by discoveries in psychological studies of the human reading process. It attempts to describe and compare the shape of the word as a whole object without trying to segment and recognize the individual characters, so it bypasses the errors committed in character segmentation and classification. However, the large number of classes and large variation and distortion expected in all patterns belonging to the same class make it difficult for conventional, accurate, pattern recognition approaches. A word shape analysis approach using ideal word patterns to overcome the difficulty and improve recognition performance is described in this paper. A special word pattern which characterizes a word class is extracted from different sample patterns of the word class and stored in memory. Recognition of a new word pattern is achieved by comparing it with the special pattern of each word class called ideal word pattern. The process of generating the ideal word pattern of each word class is proposed. The algorithm was tested on a set of machine printed gray scale word images which included a wide range of print types and qualities.

Classification of object lines in mechanical part drawings is a critical problem for automated conversion of drawings from paper medium to CAD databases. We describe new methods for classifying object lines. These methods include section line detection, hidden line detection, centerline detection and object line extraction. A self-supervised approach which includes a spacing estimation step and a recognition step to extract section lines is described. A general purpose algorithm that not only detects dashed lines but also classifies them based on their attributes is described. These attributes are used for classification of detected dashed lines as hidden lines or centerlines. Object line extraction facilitates intelligent interpretation of geometric objects for integration with CAD/CAM systems.

Conference on Nonlinear Image Processing V

Watershed transformation is used in morphological image segmentation. This transformation could be considered as a topographic region growing method. Recently, fast watershed algorithms have been proposed for general purpose computers. They are based on immersion simulations of the image surface, which is considered as a topographic relief. In such a model, the greylevel values of pixels stand for altitude values on the relief. In this paper, the operation of the present fast watershed algorithms is analyzed and a new extension is proposed. Drawbacks of the present algorithms are pointed out, studied, and illustrated with test images. These problems lead, in several cases, to a loss of information about image details and structures or even to unprocessed areas in the image. The new watershed algorithm overcomes these deficiencies and preserves more information about image details. The new algorithm is based on a split-and-merge scheme. It constantly monitors the presence of isolated areas during the immersion simulation, considering them as new catchment basins. Application of the split-and-merge watershed algorithm to marker-based image segmentation is discussed.

Document image binarization based on texture analysis

Document image binarization based on texture analysis

Document Recognition

作者： Liu, Ying Srihari, Sargur N. SUNY/Buffalo (United States)

ISBN: (纸本)081941476X

A new thresholding algorithm is presented to address strong noise, complex patterns, poor contrast, and variable modalities in gray-scale histograms. It is based on document image texture analysis. The algorithm consists of three steps. First candidate thresholds are produced from the gray scale histogram analysis. Then, texture features associated with each candidate threshold are computed from the corresponding run-length histogram. Finally, the optimal threshold is selected according to the goodness evaluation so that the most desirable document texture features are produced. Only one pass through an image is required for optimal threshold selection. The test set consisted of 9000 machine printed address blocks from an unconstrained U.S. mail stream. Over 99.6% of the images were visually well-binarized. In an objective test, a system run with 594 mail address blocks, which contains many difficult images, shows that an 8.1% higher character recognition rate was achieved, compared to that by a previous algorithm due to Otsu.
