Playing around with OpenCV

Often using OpenCV requires a lot of tweaking in parameters to get the right output. This leads to a lot of time being spent in: 1. Setting parameters, 2. Re-building and re-running your application... -_-

So I decided to play around a bit with the concept of stacking the processing procedures- at runtime, just kind of like a Photoshop for images. There is no given task I am trying at on the video itself, rather applying filter here and there. More to come... Just a good practice into integrating openCV with Qt and C++.
