That way we can remove most of the artifacts of a temporal comparison.  \nThe movement is then obtained by looking at pixels above a certain threshold in that final and image. In this version, number of pixels changing is also monitored in order to reject case with too many changes (e.g.: major background change, camera movement, etc.)\n\n# License\n\nThis script is released under the [MIT License](https://github.com/nobe4/mini-sentry/blob/master/LICENSE).\n\nOpenCV is used in respect with its [3-clause BSD License](http://opencv.org/license.html).\n\nRequests is used in respect with its [Apache License, Version 2.0](http://docs.python-requests.org/en/master/user/intro/#requests-license).\n\nAll references to TeamFortress and Valve are properties of their respective owners.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnobe4%2Fmini-sentry","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnobe4%2Fmini-sentry","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnobe4%2Fmini-sentry/lists"}
