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 17):
An apparatus comprising:\n an acquisition unit used for obtaining a gray image; a first computation unit used for obtaining a pixel threshold value of foreground pixels of the gray image as a first pixel threshold value through a global binarization algorithm; a first selection unit used for setting pixels with pixel values less than the first pixel threshold value in the gray image as first foreground pixels; a first generation unit used for setting an image formed by the first foreground pixels as a first foreground image; and a second generation unit used for binarizing the first foreground image through a local binarization algorithm, and separating and obtaining a binary image of the gray image from the first foreground image.
