Homographic motion model

edit

Hello,

I'm trying to achieve the following image:C:\fakepath\Capture.PNG

The algorithm I'm using is from: https://github.com/Itseez/opencv/blob...

which is as follows: 1. Interest points extraction 2. Interest points tracking 3. Background motion estimation.

I'm having a problem with the background motion estimation. Basically I'm trying to implement the RANSAC algorithm which should, theoretically, give the background motion estimation but I can't seem to integrate it in the code provided. Any suggestions?
