------------------------------------
[~talli...@mitre.org] Yes, we will need it for testing. I will follow up when
we reach to the testing phase.
> Supporting Image-to-Text (Image Captioning) in Tika for Image MIME Types
> ------------------------------------------------------------------------
>
> Key: TIKA-2262
> URL: https://issues.apache.org/jira/browse/TIKA-2262
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Reporter: Thamme Gowda
> Labels: deeplearning, gsoc2017, machine_learning
>
> 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!
