There should be spaces before colons in my changes, also I mistakenly add some extra spaces after `user_interface` colon. The result should be looks like this:
`'miscellaneous_transformations' : ('http://docs.opencv.org/modules/imgproc/doc/miscellaneous_transformations.html#%s', None),`
` 'user_interface' : ('http://docs.opencv.org/modules/highgui/doc/user_interface.html#%s', None),`
