Hello,

I am trying to run Template Matching code as mentioned in http://scikit-image.org/docs/dev/auto_examples/plot_template.html, however, on trying to read an image from file, it returns the following error:
ValueError: The parameter `image` must be a 2-or-3-dimensional array

Any tips on what I might be doing wrong here? tried converting image to grayscale etc.
