keras_ocr's Introduction

简介

用keras实现ocr定位、识别,后端tensorflow.

  • 环境 win10 titanx

识别

  • crnn:vgg + blstm + blsmt + ctc 原版crnn 测试速度较慢 32X280 耗时 60ms ,放弃优化。 数据集是自己造的随机数据,且比较简单。如果要测试请去这里下载 https://github.com/senlinuc/caffe_ocr 语料数据集 而且caffe_ocr的crnn更快 9ms,不知道tf和caffe差在哪里?

  • densenet-ocr :densent + ctc 无lstm 是对caffe_cor的复现 https://github.com/senlinuc/caffe_ocr (包含数据集)

网格结构 GPU 准确率 模型大小
crnn 60ms 97.2
densent+ctc 8ms 0.982 18.9MB
