Hi Prathmesh,

First of all, you have several interesting books for starting to learn OpenCV:

Apart from this, when you start to program in OpenCV, the OpenCV cheatsheet is also a very good tool:

http://docs.opencv.org/opencv_cheatsheet.pdf

Furthermore, you can use the online information about the OpenCV libraries which is very useful for solving doubts:

Finally, if you visit my personal web page you can find some related resources and papers with more advanced information about these libraries and its application in computer vision problems:

I hope that all this information helps you. Good luck with learning!

Thank You Roberto Arroyo Sir, 

I will go through all the material and if i will find some hurdle i will contact you back.

Thank you once again.
