Abstract:
A method, an apparatus and an electronic device of character segmentation are disclosed. The method includes obtaining character segmentation points of a character image to be segmented as candidate segmentation points using a predetermined segmentation point generation algorithm, the character image to be segmented being a foreground character image that is obtained by removing a background image from an original grayscale character image; selecting and obtaining correct segmentation points from the candidate segmentation points based on the original grayscale character image and a pre-generated segmentation point classifier; and performing character segmentation for the character image to be segmented based on the correct segmentation points. Using the method provided by the present disclosure, candidate segmentation points can be filtered to obtain correct segmentation points, thus avoiding overly segmentation of a character image having phenomena such as character breaking, and thereby achieving an effect of improvement on the accuracy of character segmentation.

Claim (Index 16):
The method of  claim 1 , wherein the predetermined segmentation point generation algorithm adopts a projection based character segmentation method, and obtaining the character segmentation points of the character image using the predetermined segmentation point generation algorithm comprises:\n projecting pixels in the character image onto a horizontal axis, and constructing a projection histogram; treating a respective column as a character segmentation point of the character image to be segmented if a number of pixels of a left adjacent column is greater than a number of pixels of the respective column and a number of pixels of a right adjacent column is greater than the number of pixels of the respective column for each column in the projection histogram; and if the number of pixels of the left adjacent column is greater than the number of pixels of the respective column, numbers of pixels of more than one right adjacent column are greater than the number of pixel of the respective column, and a number of pixel of a right adjacent column of a rightmost column of the more than one right adjacent column is greater than a number of pixel of the rightmost column, treating a column located in the middle between the respective column and the right adjacent column of the rightmost column as the character segmentation point of the character image.
