Embodiment Construction
[0030] Such as figure 1 As shown, it is a flow chart of the graphic text image segmentation method based on the tangential direction of the line in this embodiment, including the following basic steps:
[0031] In step 101, an initial segmentation is performed on the original image to obtain a segmented binary image. In this embodiment, first, the conventional Otsu threshold method is used to binarize the original image to obtain a binary image; then, the binary image is subjected to point filtering to remove isolated noise points in the binary result image, and the binary image after the initial segmentation is obtained. value image. The points filter uses a 3*3 sliding window, and the target points are less than the specified threshold 3.
[0032] Step 102, thinning the binary image. In this embodiment, a morphological method is used to thin the binary image; then remove false branches in the thinned binary image, and use the detected leaf nodes as lines Endpoints; Finall...
