ouyanghuiyu-chineseocr_lite's Introduction

本项目基于chineseocrpsenet 实现中文自然场景文字检测及识别

环境

pytorch 1.2.0 linux/macos

PSENET 编译

cd psenet/pse
rm -rf pse.so 
make 

实现功能

  • 提供轻量的backone检测模型psenet(8.5M),crnn_lstm_lite(9.5M) 和行文本方向分类网络(1.5M)
  • 任意方向文字检测,识别时判断行文本方向
  • crnn\crnn_lite lstm\dense识别(ocr-dense和ocr-lstm是搬运chineseocr的)
  • 支持竖排文本识别
  • ncnn 实现 psenet (未实现核扩展)
  • ncnn 实现 crnn_dense (改变了全连接为conv1x1)
  • ncnn 实现 shuuflenev2 角度分类网络
  • ncnn 实现 ocr 整个流程
  • mnn 实现
  • 提供竖排文本训练方案

web服务启动

cd chineseocr_lite## 进入chineseocr目录
python app.py 8080 ##8080端口号,可以设置任意端口

访问服务

http://127.0.0.1:8080/ocr

识别结果展示

ncnn检测识别展示(x86 cpu 单进程)

因为ncnn模型都是dense的 lstm的没转成功,效果差的不少,以后继续优化
