| titleOfInvention | A Raster Image Vectorization Method Based on Improved Flood Filling Algorithm |
| abstract | The present invention relates to a grid image vectorization method based on an improved flood filling algorithm, comprising the following steps: step S10: take an original image, perform image sharpening on it, and obtain an image containing edge information; step S20: click on the original image , using the image obtained in step S10 as a mask, fill the corresponding block by the flood filling algorithm; step S30: use the hole filling algorithm to repair the block obtained in step S20; step S40: according to the image obtained in step S30 , use the Freeman chain code contour tracking algorithm to find the coordinate point set of the block outline; Step S50: According to the coordinate point set obtained in step S40, use the polygon fitting algorithm to thin the number of coordinate points to obtain the key coordinate point set, and The lines between them are drawn in an orderly manner to form an outline to obtain the final vectorized image. The present invention has a good effect of grid image vectorization, and is compared with the grid vectorization process of manually drawing points in many places. |
