Is there a way to detect object using `OpenCV 3` in python? Once the object is detected I want to perform some task.
I have referred few links but no luck yet.
This [link](http://thecodacus.com/object-recognition-using-opencv-python/) explains it but SIFT and SURF are not available in OpenCV 3 onwards as they are patented now. Its workaround is explained [here](http://www.pyimagesearch.com/2015/07/16/where-did-sift-and-surf-go-in-opencv-3/). But it didn't work for me.
Any help would be appreciated.
Thanks.
