【问题描述】:
Tesseract 提供了一个参数来设置页面分割模式(-- psm)。
下面是所有模式,如documentation所示:
Page segmentation modes:
0 Orientation and script detection (OSD) only.
1 Automatic page segmentation with OSD.
2 Automatic page segmentation, but no OSD, or OCR.
3 Fully automatic page segmentation, but no OSD. (Default)
4 Assume a single column of text of variable sizes.
5 Assume a single uniform block of vertically aligned text.
6 Assume a single uniform block of text.
7 Treat the image as a single text line.
8 Treat the image as a single word.
9 Treat the image as a single word in a circle.
10 Treat the image as a single character.
11 Sparse text. Find as much text as possible in no particular order.
12 Sparse text with OSD.
13 Raw line. Treat the image as a single text line,
bypassing hacks that are Tesseract-specific.
-- psm 1 是否与校正图像然后使用例如-- psm 3?
【问题讨论】:
-
参考文档:tesseract-ocr.github.io/tessdoc/… 你应该在传递给 tesseract 之前对其进行纠偏
-
@K41F4r,那么 OSD 会做什么呢?
