Temple Matching with OpenCV

If you want to find an object in an image , you can use temple matching methods. I try to detect marker in video , and I try these methods. But unfortunately , temple matching methods in OpenCV are not sufficient because they are not invariant to illumination condition and scale sizes.

 You can see in my code there is a matching method , there are a lot of options , their approach like this ;

My Code ;

Result ;

As you can see in result image a rectangle appear bottom but in the middle there is me and I pasted my marker on to my chest .In video sequence nearly 30 seconds I am moving very slowly but this method cannot find right place. In this week , I will try more accurate method for recognizing object and tracking.If I do any progress, i will share the results.
