Before you proceed with this recipe, you will need to install the OpenCV 3.x Python API package and the matplotlib package. OpenCV must be built with contrib modules, because the advanced text recognition functionality isn't a part of the main OpenCV repository.
The modified .prototxt file with the model description for this recipe can be found at opencv_contrib/modules/text/samples/textbox.prototxt.
The model weights can be downloaded from https://www.dropbox.com/s/g8pjzv2de9gty8g/TextBoxes_icdar13.caffemodel?dl=0.
