### 依赖
+ Keras + Theano backend (Tensorflow data order) 请使用theano作为backend , tensorflow backend虽然权重可以载入但是识别结果是乱的
+ Theano
+ Numpy
+ Scipy
+ OpenCV
+ scikit-image
+ Keras (>2.0.0)
+ Theano(>0.9) or Tensorflow(>1.1.x)
+ Numpy (>1.10)
+ Scipy (0.19.1)
+ OpenCV(>3.0)
+ scikit-image (0.13.0)
### 设计流程
> step1. 使用opencv 的 HAAR Cascade 检测车牌大致位置
>
> step2. Extend 检测到的大致位置的矩形区域
>
> step3. 使用类似于MSER的方式的 多级二值化 + RANSAC 拟合车牌的上下边界
>
> step4. 使用CNN Regression回归车牌左右边界
>
> step5. 使用基于纹理场的算法进行车牌校正倾斜
>
> step6. 使用CNN滑动窗切割字符
>
> step7. 使用CNN识别字符

### 可识别和待支持的车牌的类型
- [x] 标准单行蓝牌
- [x] 标准单行黄牌
- [ ] 新能源车牌
- [ ] 双层黄牌
- [ ] 警用车牌
- [ ] 武警车牌
- [ ] 使馆车牌
