Embodiment one
Please refer to shown in Fig. 2,
Word cell convergent-divergent adjustment process: it comprises the basic convergent-divergent of word cell and word cell fine setting convergent-divergent, in this example, word cell fine setting convergent-divergent also can omit, but than the scheme taking word cell to finely tune convergent-divergent, slightly not enough in display effect.
The basic convergent-divergent of word cell: by the word cell size of expection, carries out convergent-divergent adjustment to the handwritten word unit of input;
The expection row height of setting handwriting input word cell is H, and the width of expection is W; Actual word cell original height of writing is OH, and original width is OW.According to the ratio of OH and H, and the ratio of OW and W, get the ratio that both are less, using this ratio as basic scaling; Or according to the ratio of OH and H, and the ratio of OW and W, get weighted mean value as basic scaling; Basic scaling can also be determined by alternate manner, carry out basic convergent-divergent.
According to the basic scaling determined, convergent-divergent is carried out to this handwritten word unit;
The basic convergent-divergent of word cell of this step, object is that to make each handwritten word unit of input be adjusted to size basically identical.
Word cell fine setting convergent-divergent: according to the dot matrix distribution characteristics of word cell, calculate scaling further, and fine setting convergent-divergent is carried out to the word cell through basic convergent-divergent;
Shown in Fig. 3, Fig. 4, the concrete steps of described fine setting convergent-divergent comprise:
First, find out the text profile rectangle of word cell: to word cell (or from the bottom up) scanning from top to bottom, obtain the first row and last column of word cell dot matrix, from left to right (or from right to left) obtain the first row of word cell dot matrix and last row, enclose by this first row and last column, first row and last row the text profile rectangle frame forming whole word cell.
Secondly, the level of confidentiality dot matrix rectangle of word cell is found out:
The level of confidentiality dot matrix rectangle of word cell can be calculated by following two kinds of modes:
Mode one: the calculating point both direction of level of confidentiality dot matrix rectangle is carried out.
In the vertical direction, scan the dot matrix number that every a line occurs from top to bottom, the dot matrix number that line number and all row are total can be calculated, obtain the overall average dot matrix number of row.
From the beginning again scan, when partial row's average dot matrix number of continuous two row (or more than two row) dot matrix number average more than the row of this overall situation, capable appearances of mark level of confidentiality dot matrix, records the position that level of confidentiality dot matrix is capable.
In the horizontal direction, scan each from left to right and list existing dot matrix number, columns and the total dot matrix number of all row can be calculated, or total dot matrix number that the columns obtained by column scan and line scanning obtain, obtain the column average dot matrix number of the overall situation.
From the beginning again scan, when column average dot matrix number more than this overall situation of the local column average dot matrix number of continuous two row (or two row more than), mark level of confidentiality lattice array occurs, the position of record level of confidentiality lattice array.
Dot matrix that is capable by level of confidentiality dot matrix and the coincidence of level of confidentiality lattice array forms a level of confidentiality dot matrix rectangle.
Mode two: scan from top to bottom, with the first row horizontal dot matrix number for standard (such as: the horizontal dot matrix number of the first row is: 3 points), when continuing down to scan, being greater than the first row horizontal line dot matrix number (when being greater than 3) when scanning the horizontal dot matrix number of certain a line, recording this horizontal line as upper side frame;
When scanning certain a line horizontal dot matrix number (from the horizontal line that last column is nearest) and being greater than last column dot matrix number (such as: the horizontal dot matrix number of last column is: 2 points), record this line horizontal line as lower frame;
Another recording mode of lower frame is as follows: scan from the bottom up, with the horizontal dot matrix number of the first row for standard (such as the first horizontal line is: 2 points), being greater than the horizontal dot matrix number (when being greater than 2) of the first row when scanning certain a line horizontal dot matrix number, recording this horizontal line as lower frame;
Scan from left to right, with the dot matrix number of first row perpendicular line for standard (such as: the dot matrix number of first row perpendicular line is: 3 points), continue scanning of turning right, when the dot matrix number scanning a certain row perpendicular line is greater than the dot matrix number (when being greater than 3) of first row perpendicular line, record this perpendicular line as left frame;
When the dot matrix number (arranging nearest perpendicular line from last) scanning a certain row perpendicular line is greater than the dot matrix number of last row perpendicular line (such as the dot matrix number of the perpendicular line of last row is: 2 points), record this row perpendicular line as left frame;
Another recording mode of left frame is as follows: scanning of turning left from the right side, with the dot matrix number of first row perpendicular line for standard (such as the first horizontal line is: 2 points), when the dot matrix number scanning a certain row perpendicular line is greater than the dot matrix number (when being greater than 2) of first row perpendicular line, record this row perpendicular line as left frame;
Above-mentioned left frame, left frame, upper side frame and lower frame intersect, and enclose formation one rectangle frame, i.e. the level of confidentiality dot matrix rectangle of word.
Finally, ratio between the size calculating the size of level of confidentiality dot matrix rectangle and the text profile rectangle of whole word cell; Again this ratio is multiplied by a Dynamic gene, the ratio of further convergent-divergent (fine setting) can be obtained.
Dynamic gene is to balance between the rectangle and word cell profile rectangle of level of confidentiality dot matrix, allows the convergent-divergent of word cell be unlikely to exaggeration.Such as, when the rectangle of level of confidentiality dot matrix and the ratio of word cell profile rectangle very little time (be less than 0.35, as " in " word), Dynamic gene is between 1.5 to 2.5.And when level of confidentiality dot matrix rectangle and word cell profile rectangle larger time (being greater than 0.85, as " state " word), Dynamic gene is between 0.6 to 1.2.This Dynamic gene is the statistical value that can draw by experiment, needs to adjust according to actual effect.
Such as, in Fig. 1 " in " word, width is little compared with desired value, and the reticular density of upper/lower terminal is low, can appropriateness amplify.The width of " state " word, highly all close to desired value, without convergent-divergent; " heart " word in upper figure, because width is comparatively large, does not need to amplify.
In certain embodiments, in the method for combination of handwriting input text importing, the dispensable step of convergent-divergent adjustment process of described word cell.In certain embodiments, in the method for combination of handwriting input text importing, the basic convergent-divergent of described word cell and the execution order of fine setting convergent-divergent are random order.
