Morph images by integrating OpenCV2.framework in iOS

Question

I am new to iOS, and I plan to work on my first application, in which I have to convert one image to another smoothly. I downloaded OpenCv2.framework and I plan to integrate into my code. I looked through some links showing the mathematical calculations needed for this, but I could not get it. Can someone please offer me some way or sample tutorial demonstrating how we can integrate and use OpenCv2.framework to convert one image to another in ios? Thanks.
