How to predict size of proposal/wedding ring from a photo

After searching a lot over internet, I couldn’t find a code which could predict the size of the proposal ring from a photograph. So, I decided to write one. Here in the version 1.0, I am using python computer vision module to do the job.

I bought a ring based on this code’s predictions and voila, she said yes!
