W e present a physics-based deformable model framework for the incremental object shape estimation and tracking in image sequences. The model is estimated by an optimization process that relates image-based cost functions to model motion via the Lagrangian dynamics equations. Although previous approaches have investigated various combinations of cues in the context of deformable model shape and motion estimation, they generally assume a fixed, known, model parameterization, along with a single model discretization in terms of points. Our technique for object shape estimation and tracking is based on the incremental fusing of point information and new line information. Assuming that a deformable model has been initialized to fit part of a complex object (e.g., a bicycle) new line features belonging to the object but excluded from the initial model parameterization are identified during tracking. The identification is based on a set of novel model-based geometric consistency checks re...

This paper presents an evaluation of eleven locally adaptive binarization methods for gray scale images with low contrast, variable background intensity and noise. Niblack's method with the addition of the postprocessing step of Yanowitz and Bruckstein's method added performed the best, and was also one of the fastest binarization methods. Keywords--- Locally adaptive binarization, Thresholding, Evaluation, Utility maps, Document images. I. Introduction T HERE is currently a large and growing interest in the field of document image analysis. Numerous research groups are trying to design systems for extracting relevant information from such diverse documents as engineering drawings, maps, magazines and newspapers, forms, and mail envelopes [1--3]. In most of these systems, binarization of the scanned gray level image (labeling each pixel print or background) is done prior to further processing. This paper will focus on binarization of map images. Maps are central to a large...

Abstract-In this work, the method of Fourier descriptors has been extended to produce a set of normalized coefficients which are invari-ant under any affine transformation (translation, rotation, scaling, and shearing). The method is based on a parameterized boundary ...
