| titleOfInvention | Text image skew correction method and system |
| abstract | The invention discloses a text image tilt correction method and system. The method includes acquiring a text image to be corrected; performing grayscale processing on the text image to be corrected to obtain a grayscale image; performing binarization processing on the grayscale image to obtain a binary image; , extract the straight line in the binary image; filter the straight line according to the length and inclination angle of the straight line; for the filtered straight line, determine the median of the inclination angle as the text image to be corrected The inclination angle of the text image to be corrected is rotated; the text image to be corrected is rotated according to the inclination angle of the text image to be corrected. The technical problem of how to effectively correct the slanted text image is solved by the embodiments of the present invention. |
