I need to perform scene text recognition with OpenCV as explained in its official documentation. However, because of some inevitable technical constraints I need to do it using the Java wrapper of the library.
I have had a look at two official examples included with OpenCV: an end to end recognition demo and one that uses the webcam. The core functionality of these examples is based on the use of an ERFilter, which performs the actual classification given an image.
I have managed to compile OpenCV's source code (version 3.1.0) with the support of the text module available at the repository of extra modules. However, I have not been able to locate an ERFilter Java class (or any equivalent functionality) within the Java wrapper that results after my compilation process. In fact, I have not been able to find any importable option similar to org.opencv.text, which is my guess on where such a class might be.
Does anyone have any idea on how to do this with the Java API provided by the compiled library?
Any approach on how to translate the official C++ code into its corresponding Java version?
Your suggestions would be very much appreciated.
