title: skimage ImageCollection and Python3
body: <p>I am having trouble using the skimage ImageCollection (<a href="http://scikit-image.org/docs/dev/api/skimage.io.html#imagecollection" rel="nofollow">http://scikit-image.org/docs/dev/api/skimage.io.html#imagecollection</a>) object in Python3. For example, in python 2,7, I was using it as follows:</p>
  
  <pre><code>import skimage.io as io
  
  files = io.ImageCollection('/home/luca/sequence/*.*)
  method_do_something(files[0])
  </code></pre>
  
  <p>This worked fine. When I use it in Python 3.4, the creation of the ImageCollection object works fine and len(files) returns the correct amount of files.</p>
  
  <p>However, when I try the files[0] call, I get the following error:</p>
  
  <pre><code>AttributeError: 'builtin_function_or_method' object has no attribute 'keys'
  </code></pre>
  
  <p>I was wondering if anyone knows of a workaround that might work on both 2.7 and python 3.x</p>
