> h2. Background:
> Image captions are a small piece of text, usually of one line, added to the metadata
of images to provide a brief summary of the scenery in the image. 
> It is a challenging and interesting problem in the domain of computer vision. Tika already
has a support for image recognition via [Object Recognition Parser, TIKA-1993| https://issues.apache.org/jira/browse/TIKA-1993]
which uses an InceptionV3 model pre-trained on ImageNet dataset using tensorflow. 
> Captioning an image is a very useful feature since it helps text based Information Retrieval(IR)
systems to "understand" the scenery in images.
> h2. Technical details and references:
> * Google has long back open sourced their 'show and tell' neural network and its model
for autogenerating captions. [Source Code| https://github.com/tensorflow/models/tree/master/im2txt],
[Research blog| https://research.googleblog.com/2016/09/show-and-tell-image-captioning-open.html]
> * Integrate it the same way as the ObjectRecognitionParser
> ** Create a RESTful API Service [similar to this| https://wiki.apache.org/tika/TikaAndVision#A2._Tensorflow_Using_REST_Server]

> ** Extend or enhance ObjectRecognitionParser or one of its implementation
> h2. {skills, learning, homework} for GSoC students
> * Knowledge of languages: java AND python, and maven build system
> * RESTful APIs 
> * tensorflow/keras,
> * deeplearning
> ----
> Alternatively, a little more harder path for experienced:
> [Import keras/tensorflow model to deeplearning4j|https://deeplearning4j.org/model-import-keras
] and run them natively inside JVM.
> h4. Benefits
> * no RESTful integration required. thus no external dependencies
> * easy to distribute on hadoop/spark clusters
> h4. Hurdles:
> * This is a work in progress feature on deeplearning4j and hence expected to have lots
of troubles on the way!
