Text skew correction
Web1 Jan 2003 · For a textual document such as that in Fig. 1 (a), these steps are repeated for every selected block in the RLSA image. The average angle of all blocks constitutes the skew angle of the whole document. The accuracy of this method depends on: 1. How much the minimum bounding rectangles of the RLSA blocks are elongated. WebThis method is straightforward by iteratively checking each angle + delta and currently only works to correct skew in the range of +/- 5 degrees. If you need to correct at a larger …
