我刚开始使用Tesseract。
我按照here所述的说明进行操作。
我创建了一个像这样的测试图像:
training/text2image --text=test.txt --outputbase=eng.Arial.exp0 --font='Arial' --fonts_dir=/usr/share/fonts
现在我想训练Tesseract如下:
tesseract eng.Arial.exp0.tif eng.Arial.exp0 box.train
这是我的输出:
Tesseract Open Source OCR Engine v3.04.00 with Leptonica
Page 1
APPLY_BOXES:
Boxes read from boxfile: 112
Found 112 good blobs.
Generated training data for 21 words
Warning in pixReadMemTiff: tiff page 1 not found
这可以防止创建fontfile.tr
文件。我已经尝试继续忽略警告,但在创建字符集时,我得到了一个令人满意的内容:
unicharset_extractor lang.fontname.exp0.box
"58

u 0 0,255,0,255,0,0,0,0,0,0 NULL 0 0 0 # u [75 ]
..."
这是我正在使用的版本:
tesseract 3.04.00
leptonica-1.72
libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8
知道为什么会这样吗?
答案 0 :(得分:0)
这可能是一个错误,我正在使用v4.00.00alpha而我
Tesseract Open Source OCR Engine v4.00.00alpha with Leptonica
