    摘要: A method for image processing includes obtaining a mask of an image; identifying, in the mask, a first stroke segment and a second stroke segment for possible merging, wherein the first stroke segment and the second stroke segment do not overlap; calculating a plurality of merger eligibility scores for the first stroke segment and the second stroke segment; calculating an aggregate merger eligibility score for the first stroke segment and the second stroke segment based on the plurality of merger eligibility scores; and merging the first stroke segment and the second stroke segment based on the aggregate merger eligibility score.

    摘要: Certain aspects of the present methods and systems may focus on computer implemented methods of obtaining digitized hand-writing data corresponding to a sample of a needed code point of a set of code points. Such methods may include: obtaining a sample of digitized handwritten text, the sample of digitized handwritten text including glyph data corresponding to a first glyph, the first glyph corresponding to the needed code point of the set of code points; associating the first glyph with the needed code point; identifying stroke data in the glyph data, the stroke data corresponding to a stroke component of the first glyph, determining a plurality of dimensional values of the stroke component in the stroke data; and associating the plurality of dimensional values with a new code point sample of the needed code point in a code point set data structure.

    摘要: A method for image processing includes obtaining a mask of a stroke from an image; determining a plurality of cross edges for the stroke based on the mask; generating a histogram comprising a plurality of widths of the cross edges and a plurality of frequencies of the plurality of widths from the cross edges; estimating a lower bound of a width range for the stroke based on a mode width of the plurality of widths, a first subset of the plurality of widths below the mode width, and a first plurality of weights assigned to the first subset of the plurality of widths; and estimating an upper bound of the width range for the stroke based on the mode width, a second subset of the plurality of widths above the mode width, and a second plurality of weights assigned to the second subset of the widths.

    摘要: The present invention discloses a system and method to recognize the geometric primitives and estimate the intended geometric relationship between the primitives. The system also provides its user an interactive feedback mechanism to better provide the graphic results intended by the user. The areas enclosed by the lines drew by the user is also considered by the system in the graphic result calculation process to improve the graphic results. One main feature of the present system is to provide geometric constraints estimations based on calculation of the constraints' effect on all related primitives and previously existing geometric constraints.
