In the latter example this is combined with the ability to crop multiple regions of the image.\n\nThe license plates recognized after each preprocess rule are combined into a single JSON response.\n\n**Poll URL for an image every 10 seconds**\n\n```\ndocker run flyingtophat/alpr http://example.com/traffic_cam \\\n  --interval 10 \\\n  --verbose\n```\n\n**Pre-process each image retrieved from URL before recognition**\n\n```\ndocker run flyingtophat/alpr http://example.com/traffic_cam \\\n  --verbose \\\n  --preprocess planar,429.000000,300.000000,-0.000000,0.000000,0.670000,1.000000,1.000000,0.000000,0.000000\n```\n\n*The rule passed in is the value generated by [OpenALPR's camera calibration](https://github.com/openalpr/openalpr/wiki/Camera-Calibration) utility. Further information on the value can\nbe found in [OpenALPR's configuration file](https://github.com/openalpr/openalpr/blob/ab1a9e20ab699fc5dec756acd44456f2d4b4c106/config/openalpr.conf.defaults) for the `prewarp` option*\n\n**Pre-process cropped regions of the image retrieved from URL before recognition**\n\n```\ndocker run flyingtophat/alpr http://example.com/traffic_cam \\\n  --verbose \\\n  --preprocess 0,0,435,299=planar,429.000000,300.000000,-0.000000,0.000000,0.670000,1.000000,1.000000,0.000000,0.000000 \\\n  --preprocess 435,0,705,299=planar,272.000000,300.000000,-0.000000,0.000000,-0.650000,1.000000,1.000000,0.000000,0.000000\n```\n\n*In this example the prewarp rules are applied to their respective cropped area (\u003cx1,y1,x2,y2\u003e=\u003cprewarp\u003e) and all license plates are combined into a single JSON response.*\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsketchingdev%2Fopenalpr-docker","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsketchingdev%2Fopenalpr-docker","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsketchingdev%2Fopenalpr-docker/lists"}
