摘要： A method for creating a template for hand-written pattern recognition comprises the steps of detecting (2) a plurality of variants of one hand-written pattern and extracting (4) individual features of the hand-written pattern. The method further comprises the steps of identifying (6) variations among the individual features in the variants of the hand-written pattern. The variations comprise variations of combinations of features in the variants of the hand-written pattern. The method further comprises the step of creating (8) the template for the hand-written pattern by establishing a cost function, said cost function weighting the individual features in accordance with the variations among the individual features. A device for hand-written pattern recognition comprises a detection means for detecting a hand-written pattern, a digitizer for transforming the hand-written pattern into a digital representation, and a reference database of templates for different hand-written patterns. The templates have been created according to the method for creating templates. The device further comprises a comparison means for comparing the hand-written pattern to templates of the reference database.

摘要： A method for recognition of a handwritten pattern comprises selecting core points among a sequence of detected points of the handwritten pattern. The core points are selected for use in segmenting and recognizing the handwritten pattern. The method further comprises determining features of each core point, and comparing the handwritten pattern to templates. The comparing comprises stepwise analyzing the core points in sequence by matching the features of sequences of core points that either start with the first core point or the last core point of a previous sequence to said templates and calculating a distance value, and assigning a cumulative distance value to the last core point in the matched sequence of core points, whereby a smallest cumulative distance value is assigned to the last core point and corresponds to a sequence of matched templates which represent a possible recognition result of the handwritten pattern.

摘要： The present invention generally describes a method for classifying a line segment of a handwritten line into a reference feature set, wherein said handwritten line comprises one or several curves representing a plurality of symbols. First, sample data representing said handwritten line is received. Next, a sample line segment in said received sample data is identified by detecting a sample line segment start point (SLSSP) and a sample line segment end point (SLSEP). Then, a sample feature set of said identified sample line segment is determined. Finally, the determined sample feature set is matched to a reference feature set among a plurality of reference feature sets.

摘要： A method for recognition of a handwritten pattern comprises selecting core points among a sequence of detected points of the handwritten pattern. The core points are selected for use in segmenting and recognizing the handwritten pattern. The method further comprises identifying potential diacritics in the sequence of points of the handwritten pattern, determining features of each core point, assigning at least one feature associated with a identified potential diacritics to each core point of a subset of core points, and comparing the handwritten pattern to templates . The comparing comprises stepwise analyzing the core points in sequence by matching the features of sequences of core points that either start with the first core point or the last core point of a previous sequence to said templates and calculating a distance value, and assigning a cumulative distance value to the last core point in the matched sequence of core points, whereby a smallest cumulative distance value is assigned to the last core point and corresponds to a sequence of matched templates which represent a possible recognition result of the handwritten pattern.

摘要： A method for presenting recognised handwritten symbols comprises the steps of recognising the detected handwritten pattern. The step of recognising comprises comparing the handwritten pattern to templates representing ways of writing symbols and returning a best interpretation of the handwritten pattern, said best interpretation being based on the pattern of a best template. At least two templates comprise different patterns which represent different ways of writing a single symbol, and the patterns of the at least two templates return different best interpretations when being most similar to the handwritten pattern. The method further comprises the step of presenting the pattern of the best template on a screen. A device for implementing the method is also disclosed.

摘要： A method for recognition of a handwritten pattern comprises the steps of forming (4) a representation of the handwritten pattern, forming (6) at least two subconfigurations by dividing the representation of the handwritten pattern, and processing the subconfigurations. The step of processing comprises the steps of comparing (8) each subconfiguration with reference configurations, selecting (10) at least one subconfiguration candidate for each subconfiguration among the reference configurations based on said step of comparing, and determining (12) at least one candidate pattern consisting of one selected subconfiguration candidate for each subconfiguration. The method further comprises the steps of comparing (14) the representation of the handwritten pattern to the candidate pattern, and computing (16) a cost function in order to find a closest matching candidate pattern. The cost function is based on the comparing of the representation of the handwritten pattern to the candidate pattern and on the comparing of the subconfigurations to the selected subconfiguration candidates in the candidate pattern.

摘要： A method for determining at least one recognition candidate for a handwritten pattern comprises selecting possible segmentation points in the handwritten pattern for use in segmenting and recognizing the handwritten pattern. The method further comprises comparing segments of the handwritten pattern to templates. The comparison returns segment candidates forming possible recognition results of the segments of the handwritten pattern. The method further comprises forming a representation of sequences of segment candidates, said representation comprising data blocks corresponding to segmentation points, wherein a data block comprises references to data blocks corresponding to subsequent segmentation points. The reference comprises information of segment candidates. The method further comprises comparing the representation of the sequences of segment candidates to a dictionary, finding sequences of segment candidates that correspond to allowed sequences of symbols in the dictionary, and returning at least one of these allowed sequences of symbols as a recognition candidate for the handwritten pattern.
