    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (504 KB)

    Cursive script recognition is problematic because of the great variability between writers and in the writing of a single individual as well as difficulties in segmenting characters. One way of depicting the reading process is to make a distinction between the letter level, the word level and the meta-word level, and to consider the different sources of information which can be utilized at each of...

    There are two fundamental characteristics in handwriting: the external shape or significant, which characterizes the author of the handwritten text; and the semantic aspect or signification, which indicates the meaning of what has been written. We focus only on handwriting recognition. We have proposed a hierarchical modelling of handwriting lines, words, allographs and ligatures, in terms of visu... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (322 KB)

    Some basics of fractal geometry are explained. Two methods for the measurement of the fractal dimension of planar curves are discussed. We present the results of applying these procedures to a number of samples of handwriting, given both in dynamic form (i.e. as time functions representing the pen movements) and in static form. An attempt to explain the fractal appearance of handwriting by means o... View full abstract»

    Non-parametric estimation of probability densities provides a useful way to realise Bayesian classifiers that may be used for example in OCR problems. The complexity of conventional kernel estimators is however far beyond the acceptable limits for performant systems. We present in this paper a novel learning vector quantization technique (IRVQ) which allows to strongly decrease the complexity of k... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (380 KB)

    This paper describes a method of representing a character according to shape profiles generated from vertical and horizontal scans through the lines of pixels constituting the character image. A pair of hidden Markov models is used to capture this shape profile information. Recognition is performed by combining knowledge from these two experts such that a test image may be "scored" against all cha... View full abstract»

    An approach is presented to use left-to-right Hidden Markov Models adopted from speech recognition for recognition of cursive script. A sequence of feature vectors is obtained from the script line deliberately doing without preprocessing to reduce writer variability. The goal is to investigate wether or not it is possible to statistically model cursive script with HMMs for recognition based on suc... View full abstract»

    One of the problems in the automatic recognition of cursive and mixed-cursive handwriting is the large variation of handwriting styles in a population. Automatic detection of the generic handwriting style, or identification of the writer could be useful to counteract this problem. The starting point for the writing style analyses is an existing recognition system for online connected-cursive handw... View full abstract»
