Docker OpenCV image
Pull requests welcome!
Dockerfile for OpenCV includes contrib modules, specifically OCR.
Out of the box this will build OpenCV 3.1.0 and include opencv_contrib modules. It will install Tesseract and Leptonica so that the OpenCV 3.x text recognition and detection modules are available.
OCR Python Bindings
The Python bindings for the text detection and recognition functions are only present from 3.1.0 onward.
