"\t" is a tab character, not a backslash followed by the letter t.  Easiest
is to use forward slashes:

    im = Image.open("C:/MATLAB6p1/toolbox/pout.tif")

You could instead use a raw string:

    im = Image.open(r"C:\MATLAB6p1\toolbox\pout.tif")

or double your backslashes:

    im = Image.open("C:\\MATLAB6p1\\toolbox\\pout.tif")

or paste path components together via os.path.join() for a wholly portable
approach.
