char-detection-'s Introduction

字符(单字)检测

效果

横版文本行 python model.py --level line --images images/0.png

横版单词,中文每个字都分割,英文按照标点符号进行分割 python model.py --level word --images images/0.png

横版字符 python model.py --level char --images images/0.png

竖版文字 python model.py --level char --images images/1.png

原理

字符出现

利用ctc loss 解析时的位置信息

crnn后处理字符出现的位置和图片的位置恰好对应,如100宽的图片处理后有10个字符,一个字符代表10像素,-s-t-aatte 第一个s起点代表10px,第二个t起点是30px,依此类推

安装和使用

安装依赖:pip install requirements.txt

使用:

单词级别:python model.py --level word

字符级别:python model.py --level char

文本行级别:python model.py --level line
