CHARACTER SEGMENTING APPARATUS, CHARACTER RECOGNITION APPARATUS, AND CHARACTER SEGMENTING METHOD |
摘要 |
A character segmenting apparatus may include a character segmenting position detecting unit to detect a segmenting position of characters. The character segmenting position detecting unit may include an area setting unit to set up an area for detecting the segmenting position; a projection creating unit configured to create a projection of pixel values, with respect to pixels arranged in a character placement direction, at least in a specified area set up by the area setting unit; a binarizing threshold value obtaining unit to calculate a moving average on the basis of minimum pixel values of the projection, in order to specify the moving average as a binarizing threshold value for the specified area; and a position detecting unit to calculate a character segmenting position on the basis of the binarizing threshold value. |

1. A character segmenting apparatus for segmenting each character out of a character string, by processing an image datum obtained by way of imaging the character string positioned on a recording medium, the character segmenting apparatus comprising:
a character segmenting position detecting unit configured to detect a segmenting position of characters constituting the character string; wherein, the character segmenting position detecting unit comprises: an area setting unit configured to set up an area for detecting the segmenting position of characters; a projection creating unit configured to create a projection of pixel values, with respect to pixels arranged in a character placement direction in which the characters are placed, at least in a specified area set up by the area setting unit; a binarizing threshold value obtaining unit configured to calculate a moving_average on the basis of minimum pixel values of the projection, in order to specify the moving average as a binarizing threshold value for the specified area; and a position detecting unit configured to calculate a character segmenting position on the basis of the binarizing threshold value obtained by the binarizing threshold value obtaining unit. |
