Here, two methods, one using Numpy functions, next one using OpenCV function (last commented line)
are given to do the same. Results are also same, but with a slight difference. Numpy gives
coordinates in **(row, column)** format, while OpenCV gives coordinates in **(x,y)** format. So
-basically the answers will be interchanged. Note that, **row = x** and **column = y**.
