If the template is in the same orientation and size as the image, then you can try normalized cross correlation. A demo is attached.
Otherwise, try Hu's moments: https://www.youtube.com/watch?v=Nc06tlZAv_Q
or the Computer Vision System Toolbox: http://www.mathworks.com/help/vision/ref/ocr.html#bt548t1-2_1
