| titleOfInvention | Method, system and equipment for extracting sliced image of field character grid in hard pen calligraphy |
| abstract | The invention belongs to the technical field of image processing, and in particular relates to a method, system and equipment for extracting sliced images of field character grids in hard-pen calligraphy, aiming to solve the problem that the current lack of methods for extracting sliced images of field characters in hard-pen calligraphy works under different image qualities hinders subsequent accurate Guide students to standardize the problem of writing Chinese characters. The method of the invention includes: acquiring a grayscale glyph image; performing local binarization on the grayscale glyph image; performing contour extraction on the binarized glyph image, and eliminating noise areas; The binarized field character grid image is used to mark the grid; the outline of the grid-marked image is extracted and the outer polygon is fitted to obtain a grid, and the grid is clustered to determine the position of the grid; based on the position extraction of the grid Field glyph slice image. The present invention realizes the extraction of sliced graphs of Zhongtian characters in hard-pen calligraphy works under different image qualities, thereby providing a technical basis for subsequent accurate guidance of students to write Chinese characters in a standardized manner. |
