Have you restarted the ElasticSearch after installing this plugin?

[bhardwajD]

what is the alternative way to image indexing and searching in ES 2.4, as elasticsearch-image is not working on the same.

Thanks in advance for the help

I suggest going with machine learning. There are many open source tools nowadays which didn't exist couple years ago. You can start from:

• Free and open source face recognition with deep neural networks. https://cmusatyalab.github.io/openface/

  This library is very extensive. Has some serious work put in it. It has Docker images to get started in minutes, has many demos/examples. Since it is for face recognition, it also covers face/object detection, indexing (actually learning via a neural network), and finally searching (again through the neural network).

• https://medium.com/@ageitgey/machine-learning-is-fun-part-4-modern-face-recognition-with-deep-learning-c3cffc121d78#.201ic8z89

  This is an amazing tutorial with up to date instructions.

• http://karpathy.github.io/neuralnets/

  Andrej Karpathy's personal blog. This guys is crazy. He explains Neural Networks as if it is just a game.

I hope this will help you get started.
