I would suggest that we make the ``sigma`` parameter of ``filters.gaussian`` optional (eg with the default value of 1), for more consistency between functions. In addition, having only one non-kw parameter, which is an image, makes introspection and testing easier.\r\n\r\nWhat do you think?\r\n"},"comment":{"url":"https://api.github.com/repos/scikit-image/scikit-image/issues/comments/226118326","html_url":"https://github.com/scikit-image/scikit-image/issues/2147#issuecomment-226118326","issue_url":"https://api.github.com/repos/scikit-image/scikit-image/issues/2147","id":226118326,"user":{"login":"ahojnnes","id":134307,"avatar_url":"https://avatars.githubusercontent.com/u/134307?v=3","gravatar_id":"","url":"https://api.github.com/users/ahojnnes","html_url":"https://github.com/ahojnnes","followers_url":"https://api.github.com/users/ahojnnes/followers","following_url":"https://api.github.com/users/ahojnnes/following{/other_user}","gists_url":"https://api.github.com/users/ahojnnes/gists{/gist_id}","starred_url":"https://api.github.com/users/ahojnnes/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ahojnnes/subscriptions","organizations_url":"https://api.github.com/users/ahojnnes/orgs","repos_url":"https://api.github.com/users/ahojnnes/repos","events_url":"https://api.github.com/users/ahojnnes/events{/privacy}","received_events_url":"https://api.github.com/users/ahojnnes/received_events","type":"User","site_admin":false},"created_at":"2016-06-15T08:12:21Z","updated_at":"2016-06-15T08:12:21Z","body":"+1 for square."}}
