Hi,
There is not a specific technique for this! You should get your hands dirty in the job!:)
Some Advice for starting:
- Get familiar with essential structures in OpenCV: Mat, Point,... and their functions and element accessing techniques while using Mat.
- Learn basic image and video i/o in OpenCV: imread, imwrite and VideoCapture class.
- There are a lot of image operation that is used widely, like filtering. So take a look at similar ways for doing them in Opencv. OpenCV has nice functions for ease of use.
- I recommend to go over OpenCV tutorial. It is nicely written and explained examples line by line!
- At last use OpenCV document a lot! It is well-ordered and in my opinion it is one of the richest references a library could have!
