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 20):
The inclined character correction method of  claim 19 , wherein calculating and obtaining the angle of inclined character correction based on the obtained predetermined edge pixels, the predetermined starting correction angle and the predetermined ending correction angle are performed by calculating an information entropy of various angles of inclination between the starting correction angle and the ending correction angle, and selecting an angle of inclination having a respective information entropy ranked at a low position to be the angle of included letter correction.
