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 9):
The method of  claim 7 , wherein binarizing the first foreground image through the local binarization algorithm, and separating and obtaining the binary character image from the first foregoing image comprise:\n for pixels in the first foreground image, separately calculating average pixel values and pixel value variances for respective sub-images having a predetermined size and the pixels as respective centers; calculating and obtaining respective pixel threshold values of the foreground image corresponding to the pixels as respective second threshold values based on the average pixel values and the pixel value variances separately corresponding to the pixels; individually determining whether a pixel value of each pixel is less than a corresponding second threshold value; setting the pixel value of the pixel as a black color if affirmative; setting the pixel value of the pixel as a white color if not; and taking the first foreground image after a pixel value update as the binary character image.
