For \"non-rolling\" mode this means treating the first detection specially and always outputting it. An additional change gives sensible behavior to rolling-window mode, generating output for every input detection.\r\n\r\nNote that when integrating this with Viame, to avoid changing behavior where not desired, users of `average_track_descriptors` should set `interval` to 1.\r\n\r\nValidation status:\r\n- First two commits on top of older VIAME / KWIVER have been run to produce reasonable results\r\n- All the changes compile on top of current `viame/master` (f1db431e1)"},"comment":{"url":"https://api.github.com/repos/Kitware/kwiver/issues/comments/437444260","html_url":"https://github.com/Kitware/kwiver/pull/648#issuecomment-437444260","issue_url":"https://api.github.com/repos/Kitware/kwiver/issues/648","id":437444260,"node_id":"MDEyOklzc3VlQ29tbWVudDQzNzQ0NDI2MA==","user":{"login":"KWCVRobot","id":29069748,"node_id":"MDQ6VXNlcjI5MDY5NzQ4","avatar_url":"https://avatars2.githubusercontent.com/u/29069748?v=4","gravatar_id":"","url":"https://api.github.com/users/KWCVRobot","html_url":"https://github.com/KWCVRobot","followers_url":"https://api.github.com/users/KWCVRobot/followers","following_url":"https://api.github.com/users/KWCVRobot/following{/other_user}","gists_url":"https://api.github.com/users/KWCVRobot/gists{/gist_id}","starred_url":"https://api.github.com/users/KWCVRobot/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/KWCVRobot/subscriptions","organizations_url":"https://api.github.com/users/KWCVRobot/orgs","repos_url":"https://api.github.com/users/KWCVRobot/repos","events_url":"https://api.github.com/users/KWCVRobot/events{/privacy}","received_events_url":"https://api.github.com/users/KWCVRobot/received_events","type":"User","site_admin":false},"created_at":"2018-11-09T18:05:03Z","updated_at":"2018-11-09T18:05:03Z","author_association":"COLLABORATOR","body":"[CentOS build succeeded.](https://open.cdash.org/buildSummary.php?buildid=5621988)"}}
