Test if Matlab can find better circles

[LinasKo]

• [x] Just do it (http://www.mathworks.com/help/images/examples/detect-and-measure-circular-objects-in-an-image.html)
• [ ] If Matlab is amazing at this, look for ways of calling its file from Python
• [x] Image might need to be normalized for it to work.
• [ ] Pass the values as circle centroids and use mask from circle corrector to find out median color values.
