Thanks for your contribution, @NSTiwari!

Could you add a brief description to your repo README on that the repo does? Any relevant references to papers or other tutorials?
For example, what's the difference between the tf.org pose estimation tutorial and your notebook? Is that you are using a different dataset?

Thanks for your feedback, @margaretmz!
I have updated my repo README with the references I used while working on the project. I would appreciate if you can review them. Thanks!
