Description

When ObjectRecognitionParser was built to do image recognition, there wasn't
good support for Java frameworks. All the popular neural networks were in
C++ or python. Since there was nothing that runs within JVM, we tried
several ways to glue them to Tika (like CLI, JNI, gRPC, REST).
However, this game is changing slowly now. Deeplearning4j, the most famous
neural network library for JVM, now supports importing models that are
pre-trained in python/C++ based kits [5].

Improvement:
It will be nice to have an implementation of ObjectRecogniser that
doesn't require any external setup(like installation of native libraries or
starting REST services). Reasons: easy to distribute and also to cut the IO
time.
