Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] The overall flow chart of the proposed method of the present invention is as figure 1 shown.
[0038] Such as figure 2 Shown is a scanned image of an example printed document. The image of the embodiment is read into MATLAB7.0 in the computer, and the im2bw function is used to perform adaptive threshold segmentation. After the obtained binary image is reversed, the bwmorph function is used to extract the skeleton, and the following is obtained: image 3 The binary feature image shown. For convenience of observation, in image 3 The feature points are represented in black, while the background points are represented in white.
[0039] Such as Figure 4 Shown is using the standard Hough transform in figure 2 The test results obtained above. In an embodiment, the discretized polar angle sequence used by the standard Houg...
