I want to get geometrical details (area, centroid, orientation, size) of images and objects in images from the video stream, what are all the algorithms available in openCV to achieve this?

And to add to that, if you actually want to look for objects first then go for one of the following techniques

Template based matching
Feature + Machine learning: HOG+SVM, cascade classifiers, ...
Bag Of Words

All these techniques are inside OpenCV!

Another good one, but in Python, is here.
