Word spotting CNN
Text Detection CNN
=================
Intro
-----
A word spotting CNN is a CNN that takes an image assumed to contain a single word and provides a probabillity over a given vocabulary.
Although other backends will be supported, for the moment only the Caffe backend is supported.
The text module now have a text detection and recognition using deep CNN. The text detector deep CNN that takes an image which may contain multiple words. This outputs a list of Rects with bounding boxes and probability of text there. The text recognizer provides a probabillity over a given vocabulary for each of these rects.
Two backends are supported 1) caffe 2) opencv-dnn
Instalation of Caffe backend
----------------------------
* Please note a custom caffe based on SSD branch is required, the link of the custom caffe is provided below
The caffe wrapping backend has the requirements caffe does.
* Caffe can be built against OpenCV, if the caffe backend is enabled, a circular bependency arises.
The simplest solution is to build caffe without support for OpenCV.

* Only the OS supported by Caffe are supported by the backend.
The scripts describing the module have been developed in ubuntu 16.04 and assume such a system.
Other UNIX systems including OSX should be easy to adapt.
