摘要： Disclosed is a character recognition preprocessing method and apparatus for correcting a nonlinear character string into a linear character string. A binarized character string region is divided into character regions on a character-by-character basis. Upper and lower feature points of each character region are derived, and an upper boundary line, which is a curve connecting the upper feature points of the character regions, and a lower boundary line, which is a curve connecting the lower feature points of the character regions, are generated by applying cubic spline interpolation. Nonlinearity is corrected through adaptive region enlargement by using the maximum horizontal length and the maximum height of the divided character regions.

摘要： Disclosed is a method of recognizing a text from an image. The method includes dividing the image into a predefined number of regions through a clustering technique; setting a certain area of the regions as a background region; identifying the outer peripheral pixel and inner peripheral pixel of each region except for the background region of the divided regions; setting a region identified as having one of its outer peripheral pixel and its inner peripheral pixel corresponding to a pixel of the background region, as a boundary region; and setting a region identified as having any of its outer peripheral pixel and its inner peripheral pixel not corresponding to a pixel of the background region, as a center text region, and excluding the boundary region from a binary-coding object of the text.

摘要： Disclosed is a method of removing staff lines from a music score an image. The method includes detecting a region with staff lines in an image including a music score; checking a gradient of the staff lines, and dividing the staff lines extending continuously in a longitudinal direction into a plurality of regions in consideration of the gradient, estimating each of the staff lines included in the divided regions by analyzing a histogram of the image, extracting each of the staff lines from the music score on the basis of the estimated staff lines and removing each of the extracted lines of the staff lines from the music score.

摘要： A method for recognizing a music score included in an image and various information included in the music score, which may be obtained through a camera provided in a mobile terminal without requiring a separate editing program. The method includes detecting a region with staff lines from the image including the music score; detecting a region with an accompaniment chord from the image by taking the region with the staff lines and a region with a musical note into consideration; extracting and removing the staff lines from the music score included in the image; recognizing the musical note by extracting the musical note from the image, from which the staff lines have been removed; recognizing the accompaniment chord by extracting the accompaniment chord from the image, from which the staff lines have been removed; and generating data for reproducing a sound source corresponding to the musical note and accompaniment chord.
